Drilling with maximum stability and direct power transfer

A Morse taper twist drill removes the full material instead of leaving a core, as an annular cutter would. This makes it practical when full material removal, precise positioning or more control is required, such as when drilling blind holes.

Compared to a standard round-shank twist drill, the Morse taper connection gives a more rigid fit between the drill and machine spindle. This supports direct torque transfer, reduces movement during heavier drilling and improves stability and control.

Once the machine is set up, Morse taper drills can be changed quickly by tapping out one drill and inserting another, making diameter changes practical.

The spiral flute design supports efficient chip removal. For steel and other metals, use the correct cutting oil or coolant to extend tool life and support hole quality and accuracy.

This type of drill is especially useful when you:
• need to drill blind holes
• need precise positioning and centring
• want more stability than with standard round-shank twist drills
• need to change between different drill diameters during the job

Available range
• MT2: Ø 15.0 mm to Ø 23.0 mm
• MT3: Ø 24.0 mm to Ø 31.0 mm
• MT4: Ø 32.0 mm to Ø 50.0 mm
• MT5: Ø 55.0 mm to Ø 75.0 mm
