Cle-Line C17043 118 Degree 45/64 in Silver & Deming Drill 1/2 Reduced Shank

Silver & Deming drill for 45/64 inch holes

The Cle-Line C17043 is a reduced-shank drill bit designed for 45/64 inch diameter work. It fits standard 1/2 inch chucks so machinists and maintenance crews can use it on common drill presses or heavy handheld drills without special tooling. The 118 degree point angle suits general-purpose drilling in ferrous and non-ferrous metals. This is a new cutting tool ready for workshop stock.

45/64 inch capacity with 118 degree point

The bit cuts a precise 45/64 inch hole and the 118 degree point centres quickly on flat stock, reducing walk at the start of the cut. Its reduced shank bridges the gap between large-hole capacity and the 1/2 inch chuck limit found on many shop machines. The high-speed steel body resists heat during moderate feeds, though very deep holes or abrasive alloys will eventually dull the edge and require resharpening or replacement.

Machining high-speed steel

The cutter is ground from machining-grade high-speed steel and carries a black and gold surface treatment that helps identify the tool and reduces surface friction. The 1/2 inch reduced shank locks securely in three-jaw chucks, minimising slip under load. No pilot hole is mandated by the design, but standard practice for this diameter still applies. The bit arrives new and ready for immediate use in metalworking applications.
