Osg 17550711 Taper Length Drill Bit 3/8 in Cobalt

Product Description

The OSG 17550711 is a taper length cobalt drill bit designed for high-performance drilling in tough ferrous and non-ferrous materials. Built from M-6K cobalt high-speed steel, it features a 120-degree split point with R-thinned web to reduce thrust and improve chip evacuation. The WXL finish provides enhanced lubricity and wear resistance. At 0.3750 inches in diameter with a fast spiral flute and tapered web configuration, this bit delivers consistent hole quality in demanding production and fabrication environments. It is suited for use by machinists, tool-and-die technicians, and metalworking professionals.

This drill bit is designed for right-hand cutting in a wide range of metals including alloy steel, carbon steel, cast iron, die steel, hardened steel, stainless steel, and aluminum. The taper length body gives additional reach compared to a jobber-length bit, making it useful in setups where standard-length bits cannot access the workpoint. The straight shank is compatible with standard drill chucks and collet holders. This bit is part of the OSG Series 1750 lineup aimed at high-performance production drilling applications.

Key Features

• M-6K cobalt construction for heat and wear resistance in hard materials
• WXL finish provides lubricity and extends tool life
• 120-degree point angle with R-thinned web reduces entry thrust
• Fast spiral flute promotes efficient chip removal
• Tapered web configuration adds rigidity along the flute length
• Straight shank fits standard drill chucks and collet holders without adapters

Compatibility

Designed as an OEM-style taper length drill bit for use in drill presses, CNC machining centers, and hand-held power tools equipped with standard straight-shank chuck systems, suitable for metalworking applications involving alloy steel, aluminum, carbon steel, cast iron, die steel, hardened steel, and stainless steel.

Installation Notes

Installation and use should be performed by qualified machinists or metalworking technicians following safe tooling practices. Secure the shank fully in the chuck or collet before beginning any drilling operation and verify runout before cutting. Power down and de-energize the machine before changing or inspecting the bit. Do not exceed the recommended speed and feed parameters for the workpiece material and bit diameter.
