M7 QA-211B Die Grinder with 1/8 and 1/4-Inch Collets
The M7 QA-211B provides two listed collet sizes for different accessory shanks rather than one interchangeable nominal size. Its straight 7.5-inch body, lever throttle and metal front cap are practical details when comparing a grinder around working clearance and attachment changes.

Before ordering
Use the correct collet for the accessory shank and check speed rating, head dimensions and material suitability. Collet inclusion does not establish an included burr or grinding stone. Confirm full air requirements for sustained use.
Product questions and answers
Can the 1/4-inch collet simply clamp a 1/8-inch shank?
Use the correctly sized supplied collet. Do not assume a larger collet safely holds a smaller shank.
Are burrs or grinding stones included?
The stated inventory identifies grinder, collets, spanners and manual. Cutting or grinding accessories are not established as included.
Does 10 CFM average consumption establish continuous demand?
No. Confirm the full operating requirements and compressor delivery for the intended work pattern.
