Walter 17mm Carbide Tipped Annular Cutter 30mm Depth

Drill Faster and Smarter with Walter Carbide Core Cutters

When you are out on a job site or in the middle of a critical fabrication project, time is money, and a dull drill bit is a welder's worst nightmare. The Walter 17mm x 30mm Carbide Core Cut (SKU: 05F117) is built to keep you working when the going gets tough. Designed for use with magnetic drilling machines, this annular cutter is a powerhouse that eats through the hardest metals, including stainless steel and cast iron, with ease. If you are tired of burning through standard HSS bits or spending half your day sharpening tools, it is time to upgrade to the durability of carbide.

Why choose carbide? It comes down to heat and hardness. Stainless steel and other tough alloys generate immense heat when drilled, which softens standard steel bits and dulls their cutting edge. The Walter 05F117 features extra-hard carbide tips that resist this heat, maintaining a razor-sharp edge long after other bits have failed. This means you can drill more holes per bit, reducing downtime for tool changes and lowering your cost per hole. The 17mm diameter is a common size for bolt holes and pass-throughs, making this a versatile addition to any welder's toolbox.

The design of this cutter isn't just about hardness; it's about smooth operation. The specialized flute geometry helps eject metal chips quickly, preventing them from packing up inside the hole. This is crucial when drilling deep into 30mm plate, as chip packing can cause the drill to bind or snap. With the Walter Carbide Core Cut, you get a smooth, consistent feed that requires less physical force from the operator. It also handles "interrupted cuts"—like drilling through two pieces of metal with a gap in between—much better than twist drills, which tend to grab and jerk the machine.

Whether you are retrofitting structural beams, repairing heavy machinery, or fabricating custom stainless tanks, this cutter delivers clean, burr-free holes that are ready for bolting immediately. No more wasting time filing down rough edges. Compatible with most standard magnetic drills, the Walter 05F117 is the reliable, high-performance choice for welders who demand professional results every time they pull the trigger.
