Sgs 61069 Solid Carbide Jobber Drill Bit 0.1260 in

Product Description

The SGS 61069 is a solid carbide jobber-length drill bit designed for precision drilling in demanding production and toolroom environments. It measures 0.1260 inches (3.20 mm) in diameter with an overall length of 2.559 inches (65.00 mm) and a flute length of 1.417 inches (36.00 mm). The 118-degree four-facet point provides accurate self-centering and clean entry, reducing the need for a center punch on most materials. Manufactured to DIN 338 standards from micrograin carbide with a bright uncoated finish, this bit is suited for machinists, tool and die workers, and CNC operators running close-tolerance hole programs.

This drill bit is appropriate for general-purpose drilling in a wide range of materials where carbide hardness and rigidity offer an advantage over high-speed steel. The straight cylindrical shank accepts standard drill chucks and collet holders. With a 5xD flute-to-diameter ratio and a maximum drilling depth of 1.102 inches (28.00 mm), it fits conventional drill presses, machining centers, and CNC milling setups. The web-thinned, tapered web design reduces thrust load and improves chip evacuation in standard spiral-flute drilling operations.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance in production drilling
• 118-degree four-facet point with web thinning for accurate entry and reduced thrust
• Bright uncoated finish suitable for a broad range of base materials
• Right-hand cut, regular spiral flute for standard chip evacuation
• Straight cylindrical shank compatible with standard chucks and collet holders
• Manufactured to DIN 338 with a diameter tolerance of +0.0000 to -0.0005 inches

Compatibility

Designed as a general-purpose replacement or production-stock jobber-length drill bit for use in standard drill chucks and collet systems accepting a 0.1260-inch straight shank.

Installation Notes

Installation and use of this bit should be performed by a qualified machinist or toolroom technician familiar with carbide tooling. Ensure the spindle and chuck or collet are fully de-energized and locked out before changing tooling. Carbide is brittle compared to high-speed steel - avoid side loading, interrupted cuts without adequate chip clearance, or excessive feed rates that can cause chipping or fracture. Verify runout and chuck concentricity before running at full speed.
