Osg 215-1960 Jobber Drill Bit No 9 Wire Size 135 Deg

Product Description

The OSG 215-1960 is a jobber-length drill bit sized to wire gauge No. 9, with a decimal diameter of 0.196 inches and an overall length of 2.252 inches. It features a 135-degree split point with web thinning, which reduces the thrust needed to start a hole and minimizes walking on entry. The two-flute slow spiral design moves chips efficiently and suits a range of metalworking applications. At 0.005 pounds, this is a compact, single-piece tooling unit suited for use in drill presses, CNC machines, and handheld power drills by machinists and fabricators working in production or maintenance environments.

This drill bit is built for general-purpose metalworking across a broad material range including steel, alloy steel, stainless steel, cast iron, aluminum silicate, nickel alloy, titanium, and titanium alloy. The straight cylindrical shank and 0.1961-inch shank diameter allow it to seat in standard three-jaw chucks without modification. The 1.188-inch flute length, combined with the slow spiral geometry and tapered web, makes it well-suited for drilling into tough or work-hardening materials at controlled feed rates.

Key Features

• Wire gauge No. 9 size with 0.196-inch decimal diameter and diameter tolerance of plus 0 to minus 0.013 mm
• 135-degree split point with web thinning reduces entry thrust and improves hole location accuracy
• Slow spiral, two-flute design promotes efficient chip evacuation in ferrous and non-ferrous metals
• Bright uncoated finish allows easy visual inspection for wear and regrinding
• Straight cylindrical shank at 0.1961 inches fits standard drill chucks without adapters
• Heavy-duty grade construction rated for general-purpose production and maintenance drilling

Compatibility

The OSG 215-1960 is designed for use with standard drill chucks accepting straight cylindrical shanks in the 0.1500 to 0.2000 inch diameter range. Primary workpiece materials include steel, alloy steel, stainless steel, cast iron, aluminum silicate, nickel alloy, titanium, and titanium alloy.

Installation Notes

This drill bit is installed and operated by machinists, toolroom technicians, and fabricators using drill presses, milling machines, or handheld power drills. Secure the shank fully in the chuck and verify runout before drilling. Use appropriate cutting fluid or coolant for stainless steel, nickel alloy, and titanium to prevent work hardening and premature edge wear. Inspect the cutting edges and web after each use for signs of wear or chipping before returning the bit to service.
