BT Morse Taper Holder

BT30, BT40 and BT50 Morse taper adapter holders for MT1 to MT6 tooling, 45 to 350mm of projection. Two forms, and picking the wrong one is the usual mistake. MTA has no draw screw — the taper alone holds a Morse taper drill or reamer, and every MTA size carries its own clamping range. MTB adds an M6 to M20 draw screw that pulls a threaded-tail Morse taper end mill up tight, which is why only the MTB sizes list a milling range. Runout is 0.012mm either way, and the shanks are cut to the MAS 403 BT spindle standard. Pull studs are not included — order the one your spindle takes. Lengths, clamping ranges and flange diameters are in the chart below.
