Brownells End Mill, Carbide, 7/16''
The Brownells End Mill, Carbide, 7/16" is a precision gunsmithing tool built for shooters and gunsmiths who machine their own parts, receivers, or custom builds. This carbide end mill handles the real work: cutting steel on the side and bottom simultaneously, which means you can plunge straight into hardened materials without the extra step of pre-drilling. That's a time-saver when you're fabricating or modifying firearm components and need clean, accurate cuts the first time.
The center-cut, four-flute design is engineered for efficiency. Right-hand helix geometry pairs with right-hand turning equipment, and the premium carbide construction handles high feed rates without sacrificing cut quality—even when you're working through tough, hardened steels common in rifle receivers and other gun parts. Whether you're opening up a magazine well, cutting chambers, or fabricating custom components, this tool is built to cut quickly and cleanly.
If you're serious about precision gunsmithing, having the right carbide tooling makes the difference between a frustrating afternoon in the shop and real progress. The 7/16" diameter gives you a versatile size for mid-range detail work on most firearm projects.

Frequently Asked Questions
What's the advantage of a center-cut design?
The center-cut, four-flute geometry allows the end mill to cut on both the side and bottom surfaces at once, which means faster material removal and the ability to plunge straight down into steel without pre-drilling a hole first. That's invaluable when you're fabricating receivers or other precision gun parts.
Can I use this on hardened steel?
Yes. The premium carbide construction is specifically designed to handle high feed rates and cut cleanly through hardened steels commonly used in firearm manufacturing and gunsmithing work.
What equipment does this work with?
The right-hand helix design is compatible with right-hand turning equipment. Confirm your mill's spindle rotation direction before use.
