The 5 Best Air-Powered Straight Line Sanders [Ranked]

A straight line sander vibrates in a straight line, rather than in circles.

It's commonly used for areas in which hand sanding is tedious or "blocking" is required. The majority are air-powered, a couple of them are electric powered (Source).

The straight line sanders we examine here are all air-powered and can provide 3,000 reciprocating strokes per minute.

How Do They Compare? 

All are twin piston with the exception of the Astro 888S Short Straight Line Sander, which is single piston (Source). 

The Ingersoll Rand straight line sander is one of our top picks. It provides 3,000 reciprocating strokes every minute, generating reliable and smooth power with quick action paper clamps. Its twin pistons ensure that it will not stall so that you can perform accurate, precise leveling and shaping of flat surfaces, and it's two-handle design makes it easy to control when it begins kicking back.

One buyer who works as a woodworking contractor, toiling over furniture and cabinets, says that he has been using this straight line sander for over a year now. He told us that he frequently works on large sanding surfaces, and prefers straight-line sanders to belt sanders because they are much easier for him to control, preventing nicking or damaging the surface material.

One buyer that we spoke with who had previous negative experiences purchasing a straight line sander from Harbor Freight at a relatively low price, was pleasantly surprised at the quality of this Ingersoll Rand straight line sander.

They compliment its fast operation and sturdy design, saying that it is a professional-quality tool that is competitively priced.

Another buyer told us that it took a little bit of time and patience to learn, but with 160 PSI feeding into it, once the pressure is regulated down appropriately there are not too many concerns about over-sanding. 

Users say that near the base of the handle you will find the air hose attachment- all you'll need to do is thread a compatible quick release nipple directly into the nut. Overall, a quality tool. Let's take a look at 5 other options.

Types of Sanders

In general, a sander is a type of power tool that is designed to smooth surfaces using sandpaper abrasion. Sanders let you attach sandpaper to the mechanism in some fashion and then rapidly move it, and are often powered by compressed air.

  • Belt sander (can be stationary or hand-held)
  • Oscillating spindle sander: A sander installed on a spindle that both rotates and oscillates out and in or down and up across the axis of the spindle. Great for sanding curves and contours that could be challenging with manual or orbital sanding.
  • Random orbital sander: The random-orbit sander is very similar to an orbital sander except that the random-orbit tool has a round pad whereas the regular issue orbital sander has a square sanding pad. The way it works, is that it randomly orbits and vibrates in tiny circles and is designed for both ultra-smooth sanding and stock removal.

    Since the pad simultaneously spins and vibrates, it actively protects against leaving behind swirls on the wood surfaces that frequently plague the functionality of regular orbital sanders.

    When purchasing, just be aware that a random-orbit sander is an able to remove wood as speedily as a belt sander can, and it is a bit more troublesome to keep control over than an orbital finishing sander.
  • Orbital sander: A hand-held sander which vibrates in small circles. The sanding disk will spin while moving concurrently in small ellipses that causes the orbital action that it is renowned for. Largely employed for fine sanding or where small material must be eradicated.
  • Straight-line sander: A sander that vibrates in a straight line, rather than in circles. Perfect for areas in which hand sanding is tedious or "blocking" is necessary. The majority are air-powered, a couple of them are electric powered.
  • Detail Sander: A hand-held sander that utilizes a tiny vibrating head using a triangular shaped sandpaper. Useful for sanding edges and incredibly restricted spaces. They are also referred to as "mouse" or "corner" sanders.
  • Table top drum sander: A bench top sander that utilizes a rotating drum. Similar to a jointer, the user changes the elevation of the grit, by altering the grit of sandpaper, to modify the degree of cut. The wood will be hand fed up against the drum to accomplish a flat, sleek surface. May be used for surface sanding, paint stripping, edge sanding, and working on cabinet door projects.
  • Stroke sander: A sizable manufacturing sander which uses a hand-operated platen on a regular sanding belt to implement pressure. For big areas including tabletops, entrance doors, and cupboards.
  • Wide-belt sander: A substantial sander comparable in principle to a planer, but much bigger. Utilizes a large sanding belt head rather than a planer's shaping head, and demands air from a separate source to tension the belt. For rough sanding substantial surfaces areas or finishing projects. Employed mainly for production furniture and cabinets.
  • Profile shaper/sander: An industrial device that includes a powered transport with a number of workstations for carrying out shaping, sanding, or any other finishing treatments on one or even more edges of elements in shelving, cabinetry, furniture etc.

    These types of devices produce and complete ornamental edges in an automatic operation making use of rotating, sanding wheels, shaping heads foil applicators along with other specialised equipment.
  • Drum sander: A big sander which uses a rotating sanding drum. In a way, much like a planer, the user adapts feed rollers to feed the wood in to the device. The sander smooths it and directs it out the opposite side. Suitable for completing huge surface areas.

What Are Buyers Saying?


Another option we examined was the PowRyte Basic 100111 pneumatic straight line sander. The manufacturers say that its twin piston design enables the tool to store extra power, which consequently prevents stalling, therefore facilitating difficult sanding projects. The 16 inch backing pad is an especially large surface area engineered to provide consistent sanding finishes on large areas.

Finely tensioned spring clamps are provided to make paper changes effortless, all powered by 3,000 reciprocating strokes per minute at 90 psi. Users we spoke we have endorsed this air-powered straight line sander for jobs like surface preparation and the rapid material removal from large surface areas.

Buyers have provided some mixed feedback for this tool though- some of them say that it's a cheap piece of junk, while others use it for residential applications as DIY hobbyists say that it is a durable option that works as well as more expensive sanders.

Another buyer who was displeased with this sander says that you would be better off purchasing from a more well-known brand that carries a strong warranty. In his opinion, the construction is shoddy and the materials are suspect- the metal that makes up its internal mechanisms are an aluminum alloy, not designed to last for a long time.

Chicago Pneumatic

The Chicago Pneumatic CP7268 straight line sander is a twin piston option that provides 3,000, 1 inch strokes per minute. Chicago Pneumatic says that it is designed to be an especially lightweight and compact option, weighing in at only 6 pounds, with an ergonomically designed handle and trigger made for a comfortable grip. One buyer we spoke with praised it as a true value-buy, saying that it provides plenty of power to leave a smooth and flat sanded surface if you know what you are doing. Indeed, this pneumatic straight line sander has received uniformly positive praise with users saying that its performance, power and durability are top notch.


Another air in-line sander we examined was the Astro 888S short straight-line sander. Astro Pneumatic Tools advertises this particular sander as being equipped to easily and smoothly feather, with a single piston that is fast and efficient, providing 3,000 strokes per minute. One home contractor we spoke with said that it has great size, but wishes that it was a dual piston tool and also dislikes that it lacks clamps for the paper. Another professional repair person said that it's a great alternative to use when your other straight-line sanders are too long.


Another option we examined was the Hutchins Hustler 2000 straight line sander. Buyers told us that it works flawlessly, that it is a bit more expensive than other options, but the consensus is that it is a high-quality option that will withstand prolonged and extended use.

Final thoughts

If you are in the market for a power sander, you should understand that there are a variety of different options on the market, including orbital sanders, belt sanders and even random-orbit sanders.

When it comes to sanding, nobody enjoys it, but purchasing a powered option can dramatically cut down on the work time, as well as provide professional-looking results. If you are looking to work on large, smooth surfaces, many home repair professionals decide to purchase a speedy and powerful belt sander. You will be able to equip it with sanding belts that are abrasive cloths that continuously loop over cylindrical drums.

Whenever you have to smooth flat boards, make sure that you perform your sanding so that it is parallel to the wood grain, doing it in this manner helps to avoid scratches. You'll want to keep the sander moving at all times, avoiding any lag as you sand the surface, and paying particular attention to smoothing narrow edges of boards.

One way to efficiently sand multiple edges is to clamp several of these boards together. This method is called gang sanding- it is able to save you a lot of time and also produce quality results as you balance the broader sanding belt on the edges of more narrow clamped together single boards. In general, as popularmechanics.com advises, belt sanders are ideal for removing varnish, stain, paint and old finish-and they also recommend beginning your sanding job with a 60 grit belt and then working your way towards finer grits until you have accomplished the degree of smoothness you were looking for.

An orbital finishing sander, on the other hand, is a relatively lightweight and maneuverable option that is not designed for heavy stock removal. It is designed for more delicate applications, vibrating in tiny and gentle circles, enabling contractors and DIY woodworkers to sand in any direction that they want.

This method of action makes it ideal for doing really smooth wood sanding, whether you are working on hard and wood putty, rounding sharp wood edges, or sanding down hardened coats of varnish or paint.
