HiPer-Drill Replaceable Tip Drill, 10XD, Diameter Range: 16 mm - 16.99 mm

Very high feed rates and maximum performance due to optimally matched geometries and materials. Precise positioning of the cutter insert due to Vee insert seating and secure clamping by the Center bore. High concentricity when assembled. Shank support for optimum stability in operation. Polished flutes. Application: For stationary and rotating use. For holes up to IT9 accuracy. Note: Clamp in a hydraulic chuck such as No. 302026 size 20 for optimum radial run-out. For optimum stability, clamp the drill so the overhang is as short as possible. Further sizes up to 0 50.99 mm available on request. The insert screw must be replaced after every fifth change of cutter insert. Reduce feed rates f by 10 % and vc values by 30 %. For process reliability when using the drill, initial pilot drilling to 1.5xD with the drill No. 231600 with the same cutter insert size and type is necessary. The generation of a pilot hole improves process reliability.
