Unibroach Annular Cutters – HSS Steel (6-Series)

Description

Faster and more accurate than twist drilling: Achieve burr-free finished holes, without predrilling or stepdrilling

Unibroach® Cutters are made of hardened, high-speed tool steel and precision-ground with up to 16 teeth for fast drilling

CS Unitec's Unibroach® Annular Cutters drill a burr-free finished hole by cutting only the material around the periphery of the hole. This forms a solid slug which automatically pops out.

• Less time and energy are consumed per hole
• Faster feed rates are achieved with more cutting teeth and less tool wear
• Lighter, less powerful drilling equipment can be used
• Able to drill holes which are difficult or impossible to do accurately with conventional twist drill tooling - with no predrilling or stepdrilling required.
