Product questions and answers
Can it take the same shanks as a quarter-inch grinder?
The established collet is 1/8 inch. Do not assume larger shanks fit or that an adapter is included.
Is an air hose supplied?
Yes. The product details list a 1,500mm air hose; that does not establish included cutting or grinding bits.
