Osg 653012912 Taper Length Drill Bit 0.1299 in Carbide

Product Description

The OSG 653012912 is a taper length, solid carbide drill bit designed for precision hole-making in demanding machining applications. At 0.1299 inches (3.30 mm) in diameter, it features a 140-degree split point angle with X-thinning for reduced thrust and improved self-centering at entry. The EgiAs coating provides enhanced lubricity and heat resistance, extending tool life in ferrous and non-ferrous materials. Coolant-through capability supports chip evacuation in deep-hole operations. This bit is built for CNC machining centers and production drilling environments where accuracy and tool longevity are critical.

The 653012912 is suited for production-floor and job-shop environments running tight-tolerance drilling in steel, stainless, aluminum, and similar workpiece materials. The 10xD flute-length-to-diameter ratio makes it well-suited for deeper hole depths without sacrificing rigidity. The straight shank at 4.00 mm (approximately 0.157 inches) fits standard collet chucks and toolholders common in CNC machining setups. It is typically installed and used by machinists and CNC operators working in precision manufacturing, aerospace, automotive, or general metalworking applications.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• EgiAs coating for improved heat resistance and extended tool life
• 140-degree point angle with X-thinning reduces entry thrust and improves centering
• Coolant-through design supports chip evacuation in deep-hole drilling
• 10xD flute-length-to-diameter ratio enables deeper hole penetration
• Right-hand spiral flute cut for standard CNC and manual machine compatibility

Compatibility

Designed as an OEM-specification taper length drill bit for use in collet chucks and toolholders accepting a 4.00 mm straight shank, compatible with CNC machining centers and drill presses configured for this shank size.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the machine fully powered down and locked out per applicable safety procedures. Ensure the straight shank is fully seated and the collet or toolholder is torqued to the machine manufacturer's specification. Verify coolant-through lines are clear and delivering adequate flow before running deep-hole cycles. Inspect the cutting edge for chips or wear before each use to prevent workpiece damage or tool breakage.
