Mikron’s CrazyDrill Cool SST-Inox Delivers More Coolant for Deeper Holes
EMO 2019: Mikron Tool’s CrazyDrill Cool SST-Inox is able to machine small diameters and deep bores in stainless steels, nickel-based super alloys and CrCo-alloys because of its internal coolant ducts, geometry and coating.
Mikron Tool’s CrazyDrill Cool SST-Inox is able to drill small diameters and deep bores in stainless steels, nickel-based superalloys and CrCo alloys because of its internal coolant ducts, geometry and coating. Its range includes through-coolant drills in diameters measuring up to 6 mm and with working lengths up to 40×D.
A chipbreaking profile at the tip of the tool creates short chips, and an enlarged flute profile in the rear section provides constant cooling and chip evacuation. To drill deeper than 10×D, the drill’s flutes are finely polished to efficiently flush out chips. The drill also has spiralized cooling ducts leading up to the drill tip. A drop-shaped rather than round cross-section promotes higher coolant volume. This cooling performance prevents overheating and subsequent chipping of cutting edges and buildup of material, according to the company.
To make the transition to hard turning, you'll need to switch from carbide to CBN inserts, but that is easier (and more economical) than you might think. It's making the jump to much higher surface speeds that might scare you off. It needn't. Here's why.
Consider these alternatives when conventional drilling can't do the job.
Simple process considerations can increase your productivity in milling titanium alloys.
