Osg 220-1495 Jobber Drill Bit Wire 25 Solid Carbide

Product Description

The OSG 220-1495 is a solid carbide jobber length drill bit in wire gauge size 25 (0.1495 inches decimal equivalent) from the OSG Series 220D. It features a 118-degree web-thinned point, a regular spiral flute, and a bright uncoated finish. The straight-cylindrical shank measures 25.00 mm in diameter. With an overall length of 2.5 inches and a flute length of 1.375 inches, this bit is designed for right-hand cutting in general-purpose drilling applications across a wide range of materials. It is installed by machinists, tool-and-die technicians, and maintenance mechanics working in production and field environments.

The 220-1495 is suited for use on steel, alloy steel, stainless steel, cast iron, aluminum, aluminum alloy, and aluminum silicate workpieces. It supports blind hole drilling, cross hole drilling, through drilling, and self-centering operations. The web-thinned point reduces thrust force at entry, which is useful when drilling harder ferrous materials. Its compact 2.5-inch overall length makes it appropriate for use in standard drill chucks and CNC machining centers where clearance is a consideration.

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous and non-ferrous materials
• 118-degree web-thinned point reduces entry thrust and improves centering accuracy
• Regular spiral flute with tapered web configuration for efficient chip evacuation
• Bright uncoated finish suitable for general-purpose use across multiple workpiece materials
• Right-hand cut with straight-cylindrical shank for compatibility with standard drill chucks
• 2-flute design balances cutting efficiency and core strength at this diameter range

Compatibility

Designed as a general-purpose OEM-style jobber length drill bit for use in standard drill chucks, collet holders, and CNC machining centers accepting straight-cylindrical shanks in the applicable diameter range.

Installation Notes

This bit should be installed by qualified machinists or maintenance technicians following standard machine-shop practices. Secure the shank fully in the chuck or collet before operation and verify runout before cutting. Coolant through is not supported on this bit; use external coolant or cutting fluid appropriate to the workpiece material when drilling stainless steel or cast iron. Inspect the cutting edges for wear or chipping before each use, as solid carbide can fracture if the bit is reused beyond serviceable condition.
