Application

Multi-spiral drill for portable use on cordless drill screwdrivers and drilling machines engineered up to a plate thickness of 5 mm.

Execution

Twist drill with special geometry for mobile use

Advantage

Three-faced polished section on the shank ensures optimum force transmission and fastening in drill chuck (no slipping through)
135° tip angle ensures very high degree of precision of the bore hole, in particular with hand-held applications in the cordless drill screwdriver thanks to the innovative centre cutting, reduced cutting forces (longer battery life) and optimum centring precision
Special coating in conjunction with relief grinding ensures maximum adhesion of the lubricant and reliable chip removal

Notes

drill Ø <4.00 mm without three-faced polished section

Delivery

Packaging unit: drill Ø 1.0-6.0 mm = 10 pieces (price per piece)
