Sgs 61062 Solid Carbide Jobber Drill Bit 0.0906 in 118 Deg

Product Description

The SGS 61062 is a solid carbide jobber length drill bit engineered for precision drilling in demanding metalworking and machining applications. Sized at 2.30 mm (0.0906 inches) in diameter with an overall length of 53.00 mm (2.0866 inches), this bit features a 118-degree four-facet point angle that promotes accurate entry and reduces walking on entry. The micrograin carbide construction delivers the hardness and edge retention required when drilling hardened steels, cast iron, stainless, and similar difficult-to-machine materials. A bright uncoated finish keeps tool prep straightforward for shops that prefer to apply their own coatings or work with cutting fluids directly on bare carbide.

This drill bit is suited for CNC machining centers, drill presses, and manual machines where tight tolerances and consistent hole quality are required. The Series 101 designation places it in a line designed for general-purpose precision drilling across a wide range of workpiece materials. It is appropriate for production shops, toolrooms, and maintenance departments handling close-tolerance work. The straight cylindrical shank seats cleanly in standard chucks and collets sized for 2.30 mm (0.0906-inch) shanks.

Key Features

• Micrograin solid carbide construction for superior hardness and edge retention versus high-speed steel
• 118-degree four-facet point angle for accurate self-centering entry and clean hole starts
• Regular spiral flute with a 5xD flute-to-diameter ratio provides efficient chip evacuation in short-to-medium depth holes
• Right-hand cut, straight cylindrical shank compatible with standard chucks and collets
• Bright uncoated finish; no coating removal required for applications using cutting fluid
• Diameter tolerance held to +0.0000 to -0.0005 inches (+0.0000 to -0.0127 mm) for consistent fit in precision holes
• Conforms to DIN 338 standard geometry

Compatibility

Designed as a general-purpose replacement or stock drill bit for machining operations requiring a 2.30 mm (0.0906-inch) diameter hole; fits any standard chuck or collet accepting a 2.30 mm straight cylindrical shank.

Installation Notes

Solid carbide drill bits should be installed by a qualified machinist or toolroom technician using a clean, properly sized collet or chuck to avoid runout that can fracture carbide at small diameters. Ensure the machine spindle is at a complete stop before changing tooling, and verify chuck or collet torque is within machine manufacturer guidelines. Carbide is brittle relative to high-speed steel — avoid side loads, interrupted cuts without proper feed reduction, and contact with other tooling during storage. Maximum drilling depth for this bit is 21.00 mm (0.8268 inches); exceeding recommended depth without pecking cycles increases breakage risk.
