Description
The Holemaker Gold Series Annular Cutters are industrial-grade magnetic drill broaches designed for high-performance metal drilling. They are widely used in structural steel fabrication and maintenance, offering a significant speed advantage over traditional twist drills.
The Holemaker Gold Series Annular Cutters feature a specialized Titanium Nitride (TiN) “Gold” coating. Manufactured from premium M2AL High Speed Steel, they are engineered to produce clean, burr-free, reamed-quality holes in steel up to ten times faster than standard twist drills. Its universal “Uni Shank” design ensures compatibility with nearly all magnetic base drilling machines.

Features:
- Titanium Nitride Coating: The Titanium Nitride coating significantly increases the tool life by providing an increased surface hardness to 85HRC, reduced friction by up to 30%, resistance to cold welding, and suitability for cutting a wide range of materials.
- M2AL High Speed Steel Material: M2AL High Speed Steel is a high alloy material with a hardness of up to 67.5 HRC, designed for increased endurance of the cutting edge and tool life.
- Step Hardened Process: This state of the art manufacturing process produces cutters with extremely hard tooth tips for increased cutter performance, while maintaining a softer body which is less susceptible to breakage than standard high speed steel cutters.
- Multi-Cut Geometry: Provides smooth and fast cutting, with decreased chatter. This also increases the cutters ability to remove swarf away from the cut, and helps to enhance centring.
- Fully Ground With Internal Relief: This feature allows Holemaker cutters to produce reamed quality, burr-free holes, and also helps to reduce torque and horsepower requirements.
- Universal Shank: 19.05mm (3/4″) Universal Shank with 2 flat sections to suit most magnetic base drilling machines.
