Feature

●Made entirely of high-alloy tool steel HSS. The split point on the drill tip ensures good centring and low feed force
●For all common industrial materials, such as non-ferrous metals, stainless steel sheets, thermoplastic and thermosetting plastics
●With this robust tool, sheets can be centred, drilled, drilled and deburred in one operation


Description

Step drill HSS, CBN ground, spiral grooved with split point. Drilling range: 4.0 mm - 12.00 mm. Shank diameter: 6.0 mm. Total length: 65.0 mm. Number of steps: 9. Areas of application: steel (n/mm2) <900, aluminium, brass and plastics. Packaging unit: individually in plastic packaging. The deep-ground and spiral flute provides absolute smoothness. he and high ung. Especially non-breaking chips are transported cleanly as with a twist drill. This reduces the formation of build-up cutting edges and cold welding on the cutting edges. The cone makes it easier to retract when the sheets are drilled through.
