BOHRCRAFT Countersinks – 1733 HSS-E Cobalt 5%, BLUE+ Coated, 90° Unequal Pitch
The BOHRCRAFT 1733 Countersink is a professional-grade tool engineered for burr-free, smooth countersinking in demanding materials. Made from HSS-E cobalt (5% cobalt alloyed high-speed steel), it provides excellent heat resistance, wear resistance, and durability, even under heavy-duty use.
Featuring a 90° cutting angle with unequal pitch geometry, this countersink reduces chatter and vibration, resulting in cleaner surfaces and longer tool life. The advanced BLUE+ coating improves hardness, minimizes friction, and allows for higher cutting speeds.
