Sgs 51773 Screw Machine Drill Bit 0.1890 in Solid Carbide

Product Description

The SGS 51773 is a screw machine length drill bit designed for high-performance drilling in demanding industrial and trade applications. Built from solid carbide with an AlTiN coating, this bit handles tough workpiece materials including alloy steels and titanium. It features a 145-degree drill point angle for aggressive, self-centering entry and a web-thinned, tapered web configuration that reduces thrust and improves chip evacuation. The straight cylindrical shank seats securely in standard chucks. At 2.625 inches overall length, it is purpose-built for short-reach, high-rigidity setups where stub length control and precision matter.

This drill bit is suited for CNC machining centers, drill presses, and manual machine operations where compact tool overhang is required. Its screw machine length profile makes it a go-to choice for machinists, tool and die technicians, and production drilling operations working in alloy steel and titanium components. The AlTiN finish extends tool life in dry or minimal-lubrication cutting environments by providing thermal and oxidation resistance at elevated cutting temperatures.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• AlTiN coating provides heat and oxidation resistance for extended tool life
• 145-degree split point angle for self-centering and reduced thrust
• Web-thinned tapered web improves chip flow and reduces feed force
• Screw machine length at 2.625 inches OAL for high-rigidity short-reach setups
• 2-flute regular spiral design optimized for alloy and titanium workpieces

Compatibility

Designed as a Series 135 high-performance screw machine length carbide drill bit for use in alloy steel and titanium workpieces across production drilling and precision machining operations.

Installation Notes

Installation is performed by qualified machinists following standard toolroom practices. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the straight cylindrical shank fully in the collet or drill chuck and verify runout before cutting. Consult machine manufacturer specifications for compatible chuck bore sizes and recommended spindle speeds for carbide tooling in the target material.
