Carbide tipped, solid carbide, and high-speed steel coolant-fed reamers

What We Do

At Proto-Cutter, our business philosophy is simple and straightforward: Provide the highest quality coolant-fed reamers and the best customer service anywhere in the industry to maximize your productivity and achieve your lowest cost per hole.

We specialize in manufacturing carbide tipped, solid carbide, and high-speed steel coolant-fed reamers in standard and special designs for precision hole finishing. Standard cutting diameter tolerances are maintained within +.00015″/-.00015″ unless otherwise specified.

In addition to our standard design right-hand spiral/right-hand cut reamers, we offer the following special flute configurations:
• Straight flute
• Left-hand spiral/right-hand cut
• Left-hand spiral/left-hand cut
• Right-hand spiral/left-hand cut

All of our reamers are manufactured to provide ease of set-up and operation. We can provide you with reamers capable of extended life, reamers that will produce an exceptionally high finish (minimizing the need for secondary operations), or a reamer that will give you a quality finish and provide you with long tool life. In addition, Proto-Cutter coolant-fed reamers eliminate chatter and other problems associated with conventional coolant-fed reamers.

Because we custom sharpen each and every reamer to its exact specified profile and tolerance, you are able to achieve hole size to within .0005”. Hole straightness can be maintained to within .0002”, depending on the hole’s depth and prior operation. With Proto-Cutter reamers, you can achieve a surface finish of 32 RMs, or even better in some circumstances. By achieving this high level of finish, our reamers eliminate the need for timeconsuming grinding, honing or burnishing operations. That means more holes reamed per year, increasing your productivity and dramatically reducing your cost per hole.

Proto-Cutter has become a trusted name in hole finishing tools because of our high quality standards, unmatched customer service, and fast lead times, which are qualities we also apply to our special made-to-print items. We are committed to providing high quality tools at affordable prices and look forward to serving all your cutting tool needs.
