BT Shrink Fit Holder

BT30, BT40 and BT50 shrink fit tool holder, runout ≤0.003mm, in 13 bore sizes from 3 to 32mm, balanced G2.5 at 25,000 rpm. 360° contact around the shank, versus the segmented contact of a collet chuck, with about three times the clamping force. The body is one piece of alloy steel with no weld, stress relieved so it takes that heat cycle again and again. The 4.5° slim taper keeps the nose clear in a tight fixture or a deep pocket, which is usually the reason to reach for shrink fit. Through-coolant jets are standard; shanks are cut to the MAS 403 taper. The pull stud is ordered separately. Bore sizes and lengths are in the chart below.
