M7 Air Die Grinder 155mm 25000rpm

A straight die grinder is one of the hardest-working tools on any workshop air line, and the M7 QA111B is built for exactly that. At 155mm long with a free speed of 25,000 RPM, it's the tool you reach for with a carbide burr for porting, deburring and edge work, or with a mounted point or small abrasive for detail grinding in places larger tools can't go.

Features and Benefits

• 25,000 RPM Free Speed: High spindle speed keeps carbide burrs and small abrasives cutting efficiently for fast, controlled material removal.
• Dual Collet Sizes: Accepts both 1/4" and 1/8" shank accessories, covering the full range of common burrs, mounted points and small grinding accessories.
• Metal Front Cap: Durable metal construction at the business end stands up to daily knocks and workshop use.
• Safety Lever Throttle: Prevents accidental start-up and gives progressive speed control under the hand.
• Compact 155mm Body: Short, slim profile for control and access in confined work.
• Air Requirements: 10 CFM at 90 PSI through a 1/4" inlet — check your compressor's free air delivery to keep it running at full performance under continuous load.

Paired with quality carbide burrs and abrasives, the M7 QA111B is a genuine all-day workhorse for fabricators, engineers and mechanics. Order online, or talk to the Wallace Heron team about matching it with the right burrs for your material.
