STRAIGHT PNEUMATIC DIE GRINDER

The Benchmark Abrasives Straight Pneumatic Die Grinder is built to put your abrasives to work in the tight, detailed areas where a full-size grinder cannot reach. Running at up to 25,000 RPM, this compact air tool is ideal for powering properly matched Benchmark Abrasives consumables for deburring, weld cleanup, metal shaping, edge work, surface preparation, and detailed finishing.

Its slim inline design gives you direct access into openings, recesses, inside edges, and confined fabrication areas, while the lightweight 0.8 lb body makes it easy to control during precision work. Pair it with the correct shank-mounted abrasive for the job and this grinder becomes a highly versatile companion to your Benchmark consumables—giving you one compact tool for aggressive material removal, detailed cleanup, blending, and finishing.

Built for Benchmark Abrasives Consumables

Use the grinder with properly matched shank-mounted Benchmark Abrasives consumables selected for the material, application, and operating speed.

Compatible consumable types may include:

• Carbide Burrs for deburring, shaping, contouring, and material removal
• Mounted Abrasives for grinding and detailed surface work
• Finishing Accessories for blending, cleanup, and surface preparation
• Other properly sized, speed-rated shank-mounted consumables appropriate for die-grinder use

Always confirm that the accessory shank exactly matches the installed collet and that the accessory's size and operating limits are appropriate for the grinder.

Why Choose a Straight Die Grinder?

25,000 RPM cutting power – High operating speed makes this tool well suited for carbide burrs and other properly matched consumables used for detailed material removal.

Straight-line reach – The inline body gets directly into openings, recesses, edges, and narrow areas that larger grinders struggle to reach.

Made to complement your abrasives – Instead of buying consumables without the right tool to run them, this grinder gives you a compact pneumatic platform for a wide range of detailed Benchmark abrasive applications.

Lightweight control – At only 0.8 lb, the grinder is easy to guide when precision matters.

One tool, multiple consumables – Change the properly matched accessory and move from aggressive deburring and shaping to blending, cleanup, and finishing.

Accessory Compatibility

Choose shank-mounted accessories that exactly match the installed collet and satisfy the grinder's speed, accessory-size, and application requirements.

Before installing any consumable:

• Match the accessory shank to the marking on the installed collet exactly.
• Use an accessory rated for at least 25,000 RPM at the intended shank overhang.
• Follow the accessory manufacturer's requirements for head size, shank insertion, and allowable overhang.
• Select the abrasive or cutting geometry for the material and job being performed.
• Never treat inch and metric shank sizes as interchangeable.

The grinder and consumable work as a system. Correct shank size, accessory dimensions, speed rating, and operating technique all matter.

The 1/4" air inlet is the air-supply connection, not the collet size.

Safety Tips

• Do not exceed 90 PSI maximum operating air pressure.
• Always wear appropriate eye, face, hearing, hand, and respiratory protection.
• Always wear appropriate eye, face, hearing, hand, and respiratory protection.
• Inspect the grinder, collet, and abrasive before every use.
• Match the accessory shank exactly to the installed collet.
• Never force an incorrectly sized accessory into a collet.
• Use only consumables rated for at least 25,000 RPM and suitable for the grinder and application.
• Follow the accessory manufacturer's requirements for insertion depth and overhang.
• Never use an accessory that is cracked, damaged, bent, or excessively worn.
• Allow the grinder to reach operating speed before contacting the workpiece.
• Maintain a secure grip and stable working position.
• Disconnect the air supply before changing consumables or servicing the grinder.
• Use dry only.
