Titan Usa TC20249 Drill Bit Size 49 Solid Carbide

Product Description

The TITAN USA TC20249 is a screw machine length drill bit designed for precision drilling in metalworking and machining applications. Built from solid carbide, this bit delivers superior hardness and heat resistance compared to high-speed steel alternatives, making it well-suited for drilling hard or abrasive materials. It features a 135-degree split point that reduces walking and allows self-centering without a center punch. The overall length is 1.5 inches, with a flute length of 0.4375 inches, and the bit cuts a 0.0730-inch diameter hole corresponding to wire gauge size 49. The straight cylindrical shank ensures secure chuck engagement across standard drill chucks and CNC toolholders.

This drill bit is used in precision machining, light manufacturing, and toolroom environments where small-diameter, accurate holes are required. The screw machine length profile — shorter than jobber length — provides added rigidity and reduced deflection, which is critical when drilling small-diameter holes in ferrous metals, stainless steel, cast iron, and similar materials. It is typically installed and operated by machinists, tool and die makers, and CNC machine operators working on close-tolerance parts.

Key Features

• Solid carbide construction for high hardness and thermal resistance in demanding materials
• 135-degree split point reduces thrust force and improves self-centering on entry
• Screw machine length body provides increased rigidity and reduced deflection versus jobber-length bits
• Bright uncoated finish compatible with a wide range of cutting fluids and materials
• Regular spiral flute geometry promotes efficient chip evacuation in through-hole drilling
• Right-hand cutting direction for use in standard drill chucks and CNC spindles

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide screw machine drill bit for applications requiring a 0.0730-inch (wire gauge size 49) hole diameter with a straight cylindrical shank.

Installation Notes

This bit is intended for installation by qualified machinists or CNC operators in appropriate drilling equipment. Ensure the drill chuck or collet is clean and properly tightened before operation. Use appropriate cutting fluid for the material being drilled to extend tool life and maintain hole quality. Solid carbide bits are brittle — avoid lateral loading, interrupted cuts without proper feed rate adjustment, and hand-held drill operation.
