EXTRA TIME Z2 Geometry
Two-flute geometry with rounded spurs and a reinforced centre point is specified by Klein for excellent finish and longer tool life.


Left-hand Klein EXTRA TIME HW dowel drill engineered for clean, repeatable boring in natural wood, pressed wood, veneered panels, chipboard, laminate, MDF, and compatible melamine or Trespa panels. The verified L115.050.L configuration uses a 5 mm diameter, 35 mm cutting length, 10×30 mm shank, 70 mm total length, and Z2 geometry.
Two-flute EXTRA TIME drilling geometry with rounded spurs and a reinforced centre point. Klein specifies Special HW cutting material, excellent finish, longer tool life, and PTFE-based coating for improved chip flow.
For compatible automatic drilling machines using a 10×30 mm shank interface and left-hand rotation. The shank design includes an adjusting screw for controlled height setup.
The Klein L115.050.L is an HW Dowel Drill EXTRA TIME Z2 from the L114-L115 family. SISTEMI Klein's current official table verifies S=10×30 mm, D=5 mm, B=35 mm, L=70 mm, and left-hand rotation for this exact SKU.
Klein specifies two flutes, rounded spurs, a reinforced centre point, Special HW cutting material, excellent finish, longer tool life, and a PTFE-based coating intended to improve chip flow. The family is suitable for natural wood, pressed wood, veneered boards, chipboard, laminate, MDF, and is also suggested for Trespa and melamine panels.
The shank design includes an adjusting screw and is intended for compatible automatic drilling machines. Confirm left-hand spindle rotation, toolholder fit, screw adjustment, runout, drilling depth, feed speed, RPM, extraction, and workpiece support before production.
Technical Specifications
Two-flute geometry with rounded spurs and a reinforced centre point is specified by Klein for excellent finish and longer tool life.
The PTFE-based coating is specified to improve chip flow while the underlying Special HW cutting material remains the active carbide cutting edge.
The exact L115.050.L configuration is 5 mm diameter, 35 mm cutting length, 10×30 mm shank, 70 mm total length, with LH rotation.
Confirm that the automatic drilling spindle accepts the exact 10×30 mm shank and requires left-hand rotation before installing L115.050.L. Verify the adjusting screw setting, tool seating, runout, drilling depth, feed speed, RPM, extraction, and workpiece support before production. A special screw for Weeke machines is available separately from Klein when required.
Klein L115.050.L combines a 5 mm cutting diameter, 35 mm cutting length, 10×30 mm shank, 70 mm total length, left-hand rotation, Z2 geometry, Special HW cutting material, and a PTFE-based coating.
Rounded spurs and a reinforced centre point support clean boring across wood and panel materials, while the adjusting-screw shank design supports repeatable setup in compatible automatic drilling machines.
