Sgs 51758 Screw Machine Drill Bit Size 32 Solid Carbide

Product Description

The SGS 51758 is a screw machine length drill bit designed for high-performance drilling in demanding materials including alloy steels and titanium. Built from solid carbide, this Series 135 bit features a 145-degree notched point with web thinning for fast penetration and reduced thrust. The AlTiN (Ti-NAMITE-A) coating provides heat resistance and extended tool life in abrasive cutting applications. At 2 inches overall length with a 0.625-inch flute length, this screw machine length format delivers rigidity and accuracy in short-reach drilling setups. It is sized at wire gauge 32, equivalent to 0.1160 inch (2.95 mm) diameter, and is suited for CNC machining centers, drill presses, and production drilling operations.

This bit is intended for use in metalworking environments where close-tolerance holes in alloy steel and titanium are required. The screw machine length profile keeps the tool short and stiff, reducing deflection in precision work. The straight cylindrical shank accepts standard collets and drill chucks. It is typically installed and used by machinists, tool and die makers, and production floor technicians working with CNC equipment or manual machine tools where short-series bits are specified for stub drilling applications.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• AlTiN (Ti-NAMITE-A) coating for elevated heat resistance and longer tool life
• 145-degree notched point with web thinning reduces thrust and improves centering
• Screw machine length (2 inches OAL) provides maximum rigidity and minimal deflection
• Right-hand cutting with regular spiral flute geometry; 2 margins for bore accuracy
• Diameter tolerance of plus 0.0002 to plus 0.0006 inches for precision hole sizing

Compatibility

Designed as an OEM-style replacement or production tooling option for screw machine length drilling applications requiring a wire gauge 32 (0.1160 inch) diameter solid carbide bit compatible with standard straight-shank collets and drill chucks.

Installation Notes

Installation and use of this bit should be performed by qualified machinists familiar with carbide tooling requirements. Secure the straight shank fully in a collet or drill chuck rated for the spindle speed and feed appropriate to the workpiece material. Carbide bits are brittle and should not be subjected to side loads or used in worn or loose tool holders. Power down and de-energize any CNC or manual machine before changing tooling.
