Solid-Carbide Construction
VHW solid carbide provides the rigid cutting structure specified by Klein for high-precision hinge boring and demanding production conditions.


Solid-carbide right-hand hinge boring bit for high-precision hinge bores in hard and soft wood, chipboard, MDF, veneered panels, and plastic-coated boards. The L155.200.R combines a 20 mm cutting diameter, 10×26 mm shank, 57 mm total length, Z2+2 geometry, and rounded spurs for clean hole quality.
Solid-carbide Z2+2 hinge-boring geometry with two cutting edges and two rounded spurs for accurate, clean hinge holes in compatible wood and panel materials.
For compatible CNC machining centres and automatic drilling machines accepting the Klein 10×26 mm shank system. The shank design includes an adjusting screw.
The Klein L155.200.R is a VHW solid-carbide hinge boring bit with Z2+2 geometry for high-precision hinge holes. The exact published configuration is D=20 mm, S=10×26 mm, L=57 mm, with right-hand rotation.
Klein specifies rounded spurs for an excellent finish and positions the L155-L156 family for high performance, including demanding production conditions. The solid-carbide construction is intended for accurate hinge boring in hard and soft wood, chipboard, MDF, veneered panels, and plastic-coated boards.
The shank design includes an adjusting screw, supporting controlled setup in compatible automatic drilling equipment. Correct spindle direction, holder condition, tool seating, drilling depth, feed rate, RPM, extraction, and workpiece support remain essential for repeatable production results.
Technical Specifications
VHW solid carbide provides the rigid cutting structure specified by Klein for high-precision hinge boring and demanding production conditions.
The Z2+2 design uses rounded spurs to define the hole perimeter cleanly and support the excellent finish Klein specifies for the L155-L156 family.
The exact 20 mm diameter, 10×26 mm shank, 57 mm total length, and RH rotation match the verified L155.200.R specification.
Confirm that the drilling spindle or boring unit accepts the exact 10×26 mm shank and requires right-hand rotation before installing L155.200.R. Verify tool seating, adjustment, runout, drilling depth, feed rate, RPM, extraction, and workpiece support before production. Use only with compatible CNC machining centres or automatic drilling machines configured for the required hinge-boring operation.
Klein L155.200.R combines a 20 mm solid-carbide cutting diameter, 10×26 mm shank, 57 mm total length, Z2+2 geometry, and right-hand rotation for high-precision hinge boring.
Rounded spurs, solid-carbide construction, and the included shank adjusting screw make this verified L155 configuration a production-focused drilling tool for wood, MDF, chipboard, veneered panels, and plastic-coated boards.
