Special Deep-Hole Drill For Installing Barrel Liners
For the gunsmith who does not want to make his own drill extension, our Hi-Speed steel drills are designed especially for deep hole drilling for Brownell Barrel Liners. The hole for the liner must be drilled slightly more than halfway from each end, and the ONLY way to ensure proper joining when using a hand drill is to use these piloted drills. Special, helix angle eliminates the tendency for the drill to “pull” itself into the material and jam, saving time and headaches. The extra cost for this premium quality drill is far cheaper than ruining a customer’s gun with an off-center hole. Given proper care, will last a lifetime.

A heavy-duty drill can make all the difference in the world in your work. The extra engineering and care in manufacture will help you to drill cleaner, more accurate holes, and many more of them at that. All the Drills we carry, Sets, Individuals, Jobber Length and Short Length, are made from High Speed Steel with a 135° self-centering point. Special point and surface treatments (Maxi-Set not treated) give easier, more wear-resistant drilling of the tough steels encountered in the gun shop.
