GARANT MasterSteel Speed Solid-Carbide Drill

The GARANT MasterSteel Speed solid-carbide drill has been designed for extreme cutting speeds and extremely high process temperatures. Thanks to a newly developed solid-carbide substrate made from ultra-micrograin together with a newly developed coating, the tool offers impressive durability even under extreme conditions.

Due to its low thermal conductivity, the coating acts like a heat shield to prevent the carbide substrate from weakening. It remains extremely hard, even under very high temperatures, in contrast to other coatings which are weakened significantly. As a result, the MasterSteel SPEED can offer the longest tool life.

Its slim chisel edge optimizes the self-centering of the drill as the material is cut to almost the very center rather than being merely displaced as is often the case. The Hoffmann Group has also pulled the guide chamfers forwards to be able to create optimal cylindrical bores. As a result, the second guide chamfer assists the drill at an early stage. The special major cutting edge reduces the cutting forces and guarantees exceptional drilling, even at high cutting speeds, meaning the MasterSteel SPEED can offer an enhanced metal-removal rate together with a long service life.

The GARANT MasterSteel SPEED is available for the range from 2 to 20 millimeters.
