Walter 4-Inch DOC Pilot Pin for 3/4 Weldon Shank Cutters

Keep Your Mag Drill Running Smoothly

Every welder knows the frustration of a magnetic drill that won't cooperate. You line up your shot, pull the handle, and suddenly you're fighting a jammed slug or a bent pin. The Walter 05Z031 Pilot Pin is designed to eliminate those headaches, specifically for your deep-hole jobs requiring a 4-inch depth of cut. When you are drilling through thick plate or structural steel, you need a pin that is long enough to reach the surface and tough enough to handle the heat and pressure. This pin is built to fit standard 3/4-inch Weldon shanks, making it a drop-in replacement for many of the heavy-duty cutters you likely already have in your shop.

The first job of this pin is to get you on target. The pointed tip lets you drop the cutter right into your center punch mark so you aren't wandering all over the steel. Once you engage the magnet and start drilling, the pin retracts smoothly into the arbor. Because Walter makes these out of hardened steel, they don't bend easily. A bent pin is a piece of junk—it rubs against the inside of the cutter, blocks the coolant flow, and eventually snaps off or ruins your expensive annular cutter. With the 05Z031, you get a straight, rigid guide that keeps the coolant flowing right to the cutting teeth where it's needed most.

The best part happens when you finish the hole. Nothing slows down a job like having to stop and wrestle a hot metal slug out of your cutter with a pair of pliers or a screwdriver. This pilot pin works with the spring in your arbor to pop that slug out automatically the second you lift the drill. It’s a simple mechanism, but when it works perfectly, it saves you minutes on every hole—and those minutes add up to hours by the end of the week. Whether you are using Walter's own cutters or another brand with compatible specs, this pin is the reliable partner your mag drill needs.

Don't let a cheap, flimsy pin shut down your production. Keep a few Walter 05Z031 pins in your kit so you are always ready for those deep 4-inch cuts. It’s cheap insurance for accurate holes and ejected slugs, every single time.
