Osg 61528 Screw Machine Drill Bit 0.1102 in Hss

Product Description

The OSG 61528 is a screw machine length drill bit designed for high-performance drilling in metal fabrication and machining applications. Built from high speed steel with a coated finish, this bit measures 2.80 mm (0.1102 inches) in diameter and features a 130-degree faceted point for accurate starting and clean penetration. The web-thinned, tapered web design reduces thrust and improves chip evacuation. At 48.00 mm overall length with a 16.00 mm flute length, the stub-length body provides rigidity ideal for short-hole drilling. Machinists and toolroom technicians working in production or repair environments will find this bit suited to precision drilling tasks.

The OSG 61528 is intended for drilling steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpiece materials. The screw machine length format is a standard choice for CNC machining centers, turret lathes, and drill presses where rigidity and repeatability matter. The straight-cylindrical shank with a 3.00 mm diameter seats securely in standard drill chucks and collets. The two-flute spiral design promotes consistent chip removal across these materials, and the 5xD flute-to-diameter ratio supports productive feed rates at appropriate cutting speeds for each workpiece material.

Key Features

• High speed steel construction with coated finish for extended tool life
• 130-degree faceted point for accurate location and reduced walking
• Web-thinned tapered web reduces axial thrust and improves chip flow
• Right-hand cut with regular spiral flutes for standard CNC and manual machine use
• Straight-cylindrical shank compatible with standard drill chucks and collets
• Diameter tolerance of plus 0 to minus 0.014 mm for precise hole sizing

Compatibility

Suited for drilling steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate. Compatible with standard drill chucks and collets accepting a 3.00 mm straight shank. Fits the OSG Series 1100 product line and the decimal inch size range of 0.1000 to 0.1500 inches.

Installation Notes

Installation and use should be performed by qualified machinists or toolroom technicians familiar with drill press, lathe, or CNC machining center operation. Secure the shank fully in the chuck or collet before initiating any spindle rotation. Select appropriate spindle speed and feed rate for the workpiece material and drill diameter per standard machining practice. Inspect the cutting edges and coating condition before each use and replace the bit if chipping or excessive wear is observed.
