FAQ

What runout (T.I.R.) can I expect?

Every KAK holder is guaranteed to 0.0003" T.I.R. or better and ships with its individual test certificate.

Will this fit my machine?

Match the taper to your spindle (BT30 or BT40) and the collet system (SK10 or SK16) to your collets. The retention knob / pull stud is machine-specific and sold separately — confirm the type your machine uses.

Are collets or pull studs included?

No. Holders are sold on their own so you can pair them with the collets and pull stud your setup already uses.

How long is shipping?

Orders typically arrive in 10–18 business days. See our Shipping Policy for details.

What if it doesn't meet spec?

Return it within 30 days for a full refund. See our Return Policy.
