Titan Usa CD44806 Jobber Drill Bit Letter F Hss

Product Description

The TITAN USA CD44806 is a Letter F jobber-length drill bit designed for production and general-purpose drilling in metal and hard materials. It measures 0.2570 inches in diameter with a 4.125-inch overall length and a 2.875-inch flute length. The 135-degree split-point tip reduces walking on entry and requires no center punch on most surfaces. The high-speed steel construction with a black oxide and TiN coating provides heat resistance and extended tool life in demanding shop environments. A two-flute, regular-spiral design promotes efficient chip evacuation during through-hole and blind-hole operations.

This drill bit is suited for drilling steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. It fits standard drill chucks via its straight-cylindrical shank and is appropriate for use in drill presses, hand drills, and CNC drilling applications where a Letter F diameter is specified. The CD44 series is commonly used by machinists, maintenance technicians, and fabricators working in light industrial and job-shop settings.

Key Features

• Letter F diameter (0.2570 inches) with tight tolerance of -0.0010 to +0.0000 inches
• 135-degree split-point tip reduces entry walking without center punching
• High-speed steel body with black oxide and TiN coating for heat and wear resistance
• Regular spiral, two-flute design promotes consistent chip removal
• Straight-cylindrical shank fits standard three-jaw drill chucks
• Maximum drilling depth of 2.875 inches; no coolant-through capability required for typical applications

Compatibility

Designed as a general-purpose replacement or stock drill bit for any application requiring a Letter F (0.2570-inch) diameter straight-shank jobber drill in high-speed steel. Compatible with workpiece materials coded P, M, K, N, and S, covering steel, stainless steel, cast iron, non-ferrous metals, and superalloys per ISO material classification.

Installation Notes

Installation is performed by machinists or maintenance technicians using a standard drill press, CNC machine, or portable drill with a compatible chuck. Secure the shank fully in the chuck and verify concentricity before drilling. Use appropriate cutting fluid when drilling stainless steel, superalloys, or titanium to manage heat buildup. Inspect the cutting edges for wear or chipping before each use and replace the bit if the split point is damaged.
