Precision Rotary Engraving Machine Cutters
Our Scott Machine micrograin carbide engraving cutters are American made, by craftspeople who take pride in their work, so you can engrave confidently and competently. These cutters produce clean, sharp letters and are ultra-durable for long-term use. They feature versatile Scott Omni-Grind™ geometry, designed to eliminate “cutter clutter” by providing universal performance across the entire line of our engraving plastics. Below we help you to choose the right cutter.
For proper sizing, choose a cutter (or "bit") width based on the height of your engraved letter. An 1/8" inch letter would use one of the two smallest bits. For lettering about 1/4" tall, a 0.030" bit is the place to start. Expand your cutter width as you increase your letter height; when you reach a 1" letter height, choose our 0.125" bit.
As a reliable supplier of engraving cutters and other engraving tools and accessories, we are happy to offer an excellent inventory, backed by superior service. So you can look forward to a wide variety of choices, with economical pricing and prompt delivery.

How to choose rotary engraving cutters?
Engraving signs and name tags in plastic is our clients' most popular activity. Using one of our ultra-sharp, carbide cutters you can expect to engrave thousands of letters. Though you can choose different cutters to create different line widths, its more efficient to choose one cutter and adjust the line width via software, to avoid interrupting the work for a cutter change.

Below we explain more about how we manufacture these cutters, and describe the benefits of solid carbide cutters versus carbide-tipped cutters.

Get the Cutting Edge with Solid Carbide
These micrograin carbide engraving cutter blanks are 1/8", 11/64" and 1/4" diameters. We only use solid carbide, the most stable cutter material, enabling the shank to remain blemish- and rust-free. For instance, they are never marred by the set-screw holding the knob.
Carbide rods never bend, so re-sharpening them always results in a "like new" cutting edge, true to size and form. And because carbide dissipates heat very rapidly, it can hold consistently tight tolerances from tool to tool in the manufacturing process.

Scott Omni-Grind™ Reduces Cutter Clutter
The exacting Omni-Grind™ geometry of our precision cutters affords engraving that produces clean-edged, swirl-free letters in all engraving plastics, on a wide range of engraving machines and speeds – with a single blade. This eliminates the need for multiple cutters that overcomplicate the cutting process.
Our rotary engraving cutters are accurately sharpened with the perfect relief angle. The cutter tips are ground according to the material being engraved. So a cutter being used for engravable plastic has a greater clearance behind the cutting edge than one being used for steel. As the material becomes harder, the angle decreases, giving the cutting edge more strength.
Crafted right in our upstate New York factory, our engraving cutters still fit many earlier model engraving machines that you might own.
