The Oliver Model 600 Drill Point Grinder is the ideal machine for sharpening large diameter bits from 1/2″ to 3″ (76 mm), with the option to increase the maximum drill size to 4″ (102 mm). The machine easily handles two flute, three flute and four flute drill bits. Variable included point angels are readily obtained and variable clearance or lip relief angles can be dialed in. The geometry that is best suited for your manufacturing procedures can be added to your drills easily and quickly.
A revolving chuck and oscillating grinding wheel spindle are coordinated with a direct gear positive drive. All of the movements involved with sharpening are automatic.
The Model 600 Automatic Drill Grinder is supplied with an airdraulic infeed unit that allows the operator to select the rate of infeed and the total amount of stock removal. This feature, combined with the automatic grinding cycle, permits the unit to function without an operator once the loading and operating sequence has been completed. This eliminates the chance of operator error that comes with swing grinding large bits. The machine is also supplied with a tank, pump, splash guards and piping to provide coolant to the grinding area.

The Oliver 600 creates a precision helical drill point, which provides superior penetration and longevity in comparison to a point created by a typical “swing grind” style grinder. In many applications, the Oliver helical point reduces the torque and thrust required by over 20%, resulting not only in a longer lasting bit, but a longer lasting drill machine as well due to less wear and tear. More holes drilled per grind means less downtime that can result in a substantial cost savings. This heavy duty, powerful and rigid grinder will cover a wide range of applications and provide many years of reliable service.
