Titan Usa TC29211 Screw Machine Drill Bit 0.1910 in

Product Description

The TITAN USA TC29211 is a screw machine length drill bit designed for high-performance drilling in metal, hardened steel, stainless, and other demanding materials. Built from solid carbide and coated with an aluminum titanium nitride (AlTiN) finish, this bit delivers extended tool life and heat resistance in production and shop environments. It carries a wire gauge size of 11, equal to 0.1910 inches in diameter, with an overall length of 2.5 inches and a 135-degree split point that reduces walking and enables fast, precise entry without a center punch. Machinists, tool-and-die technicians, and CNC operators are the primary installers and users of this type of tooling.

This drill bit is suited for screw machine work, CNC drilling operations, and manual drill press applications where a compact overall length is required for close-tolerance work or limited spindle clearance. The shorter body of screw machine length bits provides added rigidity compared to jobber length, reducing deflection on tight-tolerance hole patterns. It is applicable in metalworking, fabrication shops, and precision machining environments that require consistent hole quality in harder workpiece materials.

Key Features

• Solid carbide construction for hardness and wear resistance in ferrous and non-ferrous metals
• AlTiN coating extends tool life and improves performance at elevated cutting temperatures
• 135-degree split point reduces thrust force and eliminates center-punch requirements
• Screw machine (stub) length body provides increased rigidity and reduced deflection
• Right-hand cut with regular spiral flutes for efficient chip evacuation
• Straight shank compatible with standard drill chucks and collet holders

Compatibility

Designed as an OEM-style replacement and standard tooling option for CNC machining centers, drill presses, and screw machines that accept straight-shank drill bits in the 0.1500 to 0.2000 inch diameter range.

Installation Notes

Installation is performed by machinists and tool-room technicians. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the straight shank fully and evenly in the chuck or collet before tightening to prevent runout. Do not exceed the recommended surface footage for solid carbide tooling in the workpiece material, as dry-running carbide at incorrect speeds can cause premature chipping or failure.
