BT-SLN Side Lock End Mill Holder

BT side lock end mill holder for straight shanks, 6 to 25mm on BT30, 6 to 42mm on BT40 and 6 to 50.8mm on BT50, with an H5 bore. A hardened screw bears on the Weldon flat of the shank, so drive torque goes through steel on steel instead of friction — which is why a side lock arbor is still holding the cutter in a roughing pass where a collet chuck has begun to slip. The taper is cut to the MAS 403 taper BT. Gauge lengths run 75 to 350mm, and the lock screw is sized to the bore, M6 on the smallest through M20 on the 50.8mm. The trade-off is one shank size per holder: you buy a holder per end mill diameter, and in return the tool does not creep out under load. The pull stud is ordered separately.
