An annular cutter is commonly used to drill holes in ferrous and non-ferrous metals. These cutters are cylindrical shaped, hollow and feature multiple cutting edges. The hollow centre makes annular cutters highly effective because there is no dead-zone resistance. The holes created by annular cutters are burr-free, and no pre-drilling or step drilling is required for improved drilling quality and efficiency.
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 lesssusceptible to breakage than standard high speed steel cutters.
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.
19.05mm (3/4"") universal shank for cutters up to and including 60mm diameter. Featuring 2 flat sections to suit most magnetic base drilling machines. Cutters of diameters 61mm and above feature a 31.75mm, 1-1/4" Weldon shank. 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.
