Osg 8666300 Screw Machine Drill Bit 13mm Solid Carbide

Product Description

The OSG 8666300 is a solid carbide screw machine length drill bit designed for high-performance drilling in demanding materials. With a 13 mm diameter and a 140-degree split point, this bit delivers fast, accurate penetration with reduced thrust and minimal walking on entry. The overall length is 128 mm (approximately 5.04 inches), and the flute length is 65 mm, placing it in the short, rigid screw machine class. Coolant-through capability supports chip evacuation and tool life in deep-hole and production drilling. Right-hand cut with a straight-cylindrical shank at 13 mm diameter. This bit is installed by machinists, tool-and-die technicians, and maintenance professionals in CNC and manual drilling applications.

The 8666300 belongs to OSG Series 5200 and is rated for use in steel, stainless steel, cast iron, titanium, and titanium alloys. It suits production environments where short cycle times and consistent hole quality are required. The 3xD flute-to-diameter ratio and R-thinned, tapered web configuration reduce cutting forces and improve chip flow in tough materials. Typical applications include component drilling on machining centers, drill presses, and multi-spindle setups in industrial manufacturing and metalworking shops.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• 140-degree point angle reduces entry thrust and prevents bit walk on flat and curved surfaces
• Coolant-through design supports internal chip evacuation and extended tool life in production runs
• R-thinned, tapered web lowers cutting forces and improves performance in stainless steel and titanium
• Straight-cylindrical shank at 13 mm diameter for direct collet or drill chuck mounting
• 3xD flute ratio in screw machine length provides maximum rigidity in short-reach setups

Compatibility

Designed for use in steel, stainless steel, cast iron, titanium, and titanium alloys. Fits any CNC machining center, drill press, or multi-spindle machine with a collet or chuck accepting a 13 mm straight-cylindrical shank. Part of the OSG Series 5200 high-performance carbide drill family.

Installation Notes

Machining professionals should verify spindle speed and feed rate against material hardness and coolant availability before use. Ensure the coolant-through supply is active before starting the cut when using internal coolant to prevent premature tool wear. Secure the shank fully in a matched collet or drill chuck to minimize runout. Inspect the cutting edges and point geometry for chips or wear before each production run.
