Holds tighter hole size - The split point design is self centering. This limits the normal oversize drilling characteristics. Outstanding quality appearance - The rich amber gold color sets it apart from commodity cutting tools. Runs cooler, uses less torque - 135 degrees point takes a smaller chip resulting in less heat. Friction is reduced by amber gold surface treatment.
Stops chuck slippage - Flats on drill shanks allow easy positive chuck grip.
The Magnum drills will substantially outperform cobalt drills in work hardening stainless steel applications. This performance advantage is the result of construction differences between the two types of drills. Cobalt drills, manufactured to Type J NAS 907 specs, have a very thick web. This web is necessary to limit breakage of the brittle cobalt steel. Magnum drills are made of special hi-moly tool steel, which is much tougher than cobalt steel.
