Titan Usa CD30029 29/64 in Screw Machine Drill Bit Hss

Product Description

The TITAN USA CD30029 is a screw machine length drill bit designed for high-speed steel cutting in metal fabrication, maintenance, and production drilling applications. Built from heavy-duty high speed steel with a black oxide finish, this bit measures 29/64 inch (0.4531 inches) in diameter and features a 135-degree split point for self-centering starts without a center punch. The shorter screw machine length body reduces deflection and increases rigidity compared to jobber-length bits, making it well suited for close-clearance work in drill presses, CNC machines, and hand drills. Two spiral flutes evacuate chips efficiently throughout the 2.125-inch flute length.

This bit is used in general metalworking, fabrication shops, maintenance and repair operations, and light production environments. The straight-cylindrical shank provides secure clamping in standard three-jaw chucks and quick-change systems. At 0.4531 inches, the bit falls in the 0.45 to 0.50 inch size range and is commonly selected by machinists, millwrights, and HVAC or plumbing tradespeople drilling through structural steel, pipe, and sheet metal during installation or retrofit work.

Key Features

• 135-degree split point for self-centering starts and reduced thrust
• Heavy-duty high speed steel construction for durability in ferrous metals
• Black oxide finish reduces friction and provides light corrosion resistance
• Screw machine length body increases rigidity and reduces deflection
• Two spiral flutes for efficient chip evacuation
• Straight-cylindrical shank fits standard drill chucks and quick-change holders

Compatibility

Designed as a screw machine length replacement bit for standard three-jaw chucks and quick-change chuck systems accepting straight-cylindrical shanks in the 29/64 inch diameter class.

Installation Notes

Installation should be performed by qualified machinists or tradespeople familiar with drilling operations. Secure the shank fully in the chuck and verify concentricity before starting the cut. Use appropriate cutting fluid for the material being drilled to extend tool life and improve hole finish. Inspect the cutting edges before each use and replace the bit if chipping or excessive wear is observed.
