Osg 215-3750 Jobber Drill Bit 3/8 Inch 135 Degree Point

Product Description

The OSG 215-3750 is a 3/8 inch jobber-length drill bit designed for general-purpose drilling in metalworking and fabrication applications. It features a 135-degree split point with web thinning for fast penetration and reduced walking at entry, eliminating the need for a center punch on most surfaces. The slow spiral flute geometry controls chip evacuation in deeper cuts, while the straight cylindrical shank seats securely in standard drill chucks and CNC toolholders. With an overall length of 3.126 inches and a flute length of 1-13/16 inches, this bit suits a wide range of bench drill, handheld drill, and machining center setups. Licensed machinists, toolroom technicians, and fabricators are the primary installers.

The 215-3750 is built for drilling into a broad range of primary workpiece materials including steel, alloy steel, stainless steel, cast iron, aluminum silicate, nickel alloy, titanium, and titanium alloy. The Series 215 design targets general-purpose production and maintenance environments where a single bit must perform reliably across varied material hardness. The bright uncoated finish keeps regrinding straightforward and makes wear inspection easy during tool life monitoring. This bit is sold individually and fits standard 3/8 inch chuck capacity or collet systems.

Key Features

• 135-degree split point with web thinning reduces thrust and prevents walking at drill entry
• Slow spiral flute geometry improves chip control in steel and harder alloys
• Bright uncoated finish simplifies regrinding and wear inspection
• Straight cylindrical shank fits standard drill chucks and collet toolholders
• Tapered web configuration adds rigidity along the flute length
• General-purpose Series 215 design covers a wide range of metallic workpiece materials

Compatibility

Compatible with primary workpiece materials including steel, alloy steel, stainless steel, cast iron, aluminum silicate, nickel alloy, titanium, and titanium alloy. Fits any drill press, handheld drill, or machining center equipped with a 3/8 inch chuck or matching collet. Suitable for applications within the 0.3500 to 0.4000 decimal inch drill bit size range.

Installation Notes

Installation is performed by machinists, toolroom technicians, or maintenance fabricators. Secure the shank fully in the chuck or collet before operation and verify runout before cutting. Always wear appropriate eye protection and follow facility lockout procedures when changing tooling on powered equipment. Do not exceed the recommended feed and speed parameters for the workpiece material to avoid premature tool wear or breakage.
