How to Sharpen a Drill : Oliver of Adrian

SUCCESS IN DRILL SHARPENING BY UTILIZING A DRILL SHARPENING MACHINE

A drill bits success is measured by the tools ability to penetrate the material as quickly as possible and with minimal waste. The critical factor of the drill bit is the point of the drill. Like a screw, the drill point, will dull with use. A screw’s ridges, just like the lips of the drill, may lose its accuracy. Equal conditions of each lip of the drill are essential to cleaner and more defined holes.

The Oliver Drill Point Thinner, used in conjunction with the Oliver Drill Grinder allows drills to perform for a greater length of time.

How to Sharpen a Drill

Traditionally when one thinks of sharpening drill bits, the first thing that comes to mind is sharpening a drill by hand. This is especially true with large drills. Over 100 years ago (before Oliver was founded) this was many times the only option. Here the grinding of the drill was accomplished generally with a bench grinder. The skilled tradesman would attempt as much as possible to generate the needed point with a keen eye and slight of hand. What Edd Oliver (founder of Oliver of Adrian, Inc.) realized was that even the most skilled tradesman had a challenge with consistently producing the perfect drill point needed for modern manufacturing. Thus the stage was set and the challenge was given “Can we do it better with a drill grinding machine?” As it was true 100 years ago, as it is today, with an Oliver Drill Grinder, the perfect helical generated point was created!

This is where Oliver has thrived for 100 years as the industrial drill sharpener specialist. In manufacturing, many times, the industrial drill is one of the most essential tools. Where Oliver has staked its claim, is that many manufacturers are required to sharpen their drills frequently throughout the day. Those that tend to buy Oliver Drill Grinders use their drill multiple times a day and also appreciate owning the highest quality drill grinder in the world.

For the finest in drill sharpening machines there is no better choice than Oliver of Adrian, Inc.

The theoretically perfect Oliver point will give you the many advantages that automatically come with reduced torque and thrust during your drilling operations. We sharpen all cutting lips in one continuous automatic motion regardless of whether you are considering two flute, three flute or four flute drills. Further, we have variable included point angles and variable lip relief angles immediately available to give you the proper grind for the material involved. The Model 600 Drill Grinder is available in either the semi-automatic or automatic style.

The Model 700 Drill Grinder is a more automatic machine than the Model 600 Drill Pointer. A push button is used to start the machine. After the drill is placed in the chuck, another button is pushed to set the machine into automatic operation rather than a manual motion. There is a push button that automatically generates the self-centering point on the drill. These more fully automated features plus esthetic appearance are basically the differences between the Model 700 and Model 600.

The major advantages of the Oliver Model 700 compared to the Oliver Model 600 are:

The automatic self-centering feature instead of having to manually advance the chuck.
Push button controls instead of a mechanically actuating arm.
The push button controls include: spindle start/stop, wheel oscillation start/stop, self-centering at a push of a button, and emergency stop.

The Oliver can grind many types of tools including center drills, oil-hole drills, parabolic drills, track bits, core drills and spade drills in both HSS drills and carbide.
