Shaft For TREPA+ Ø31 to 100 - 3 Flats Ø10

Shaft For TREPA+ Ø31 to 100 - 3 Flats Ø10

The FTHAR03 drive arbor is designed for use with FTHL and FTAL hole saw cutters from Ø31 to 50 mm. Its screw-on connection provides a reliable assembly for drilling operations in workshops, industrial maintenance environments and on-site applications.

The 12 mm 3-flat shank supports a stable hold inside the drill chuck and helps reduce slipping during machining. This profile promotes consistent torque transmission when drilling resistant materials.

The Ø6 x 50 mm HSS pilot drill guides the cutter from the start of the operation. It helps position the hole accurately, stabilises the tool and supports the hole saw as it moves through the material.

Designed for professional use, the FTHAR03 can be used on mild steel, alloy steel, non-ferrous metals, hard plastics, cast iron and different types of wood. It provides a dependable mechanical connection between the drilling machine and the hole saw cutter for clean, controlled drilling.
