SOLID CARBIDE DRILL BIT

The Brownells Solid Carbide Drill Bit is a precision-engineered tool designed to tackle the challenges of drilling into hardened steel components commonly encountered in firearms, such as the 03A3 receivers. Its specialized single-flute design ensures clean, accurate holes without causing chatter or work hardening, making it an indispensable asset for professional gunsmiths.

Key Features:

Single-Flute Design: This unique design allows the drill to cut clean chips in the hardest file steel, ensuring true and precise holes without causing chatter or crumbling of the material.
Optimal Length: Measuring 2 inches in length, the drill provides adequate quill clearance when used with scope or sight mounting jigs, facilitating ease of use in various gunsmithing setups.
Efficient Performance: When properly maintained, the drill resists binding or breaking. Its design prevents work hardening of the hole surface, thereby reducing the likelihood of tap breakage during subsequent threading operations.

Specifications:

Material: Solid carbide construction for enhanced durability and longevity.
Available Sizes:

No. 31 (6-48)
No. 28 (8-40)

Recommended Usage: Ideal for drilling through hardened steels; not recommended for use in softer steels. Should be employed when other drills have failed or when the hardness of the steel is known to be challenging.

Carbide drill #31

I have not used this # yet, I am replacing another brand that did not do the job and was way too short, but it is 2" in length and if it cuts like the #28 I used on a 03A3 receiver, it's worth the price. Thank you

Solid carbide drill

Nothing is more irritating than trying to get a scope base drilled in a hardened rifle receiver and having the hole oversized due to drill walking. This carbide drill solves that problem handily. Bites right in!

Last resort

Works well for drilling out stuck plungers. This is the bit you go to when all else fails.

When the going gets tough

Great for drilling out stuck plungers. Works well on hardened receivers as well. If you work on firearms with any regularity you ought to have one in the shop - someday you'll be glad you have it at hand.

case-hardened Krag receiver

I used this bit to drill a Krag for a receiver sight. It cut through it like a hot knife through butter.

Worked as desired!

Bought this after various attempts to remove a broken tap to n a receiver. Tried all the broken tap removal tools. There is truly no tried and true solution tool. Everyone breaks a tap - so one might think THE fix it tool exists. Bottom line is with some patience, a slow hand/feed, this bit worked as I needed. Good luck with your broken tap.
