Sgs 51013 Jobber Drill Bit 0.185 in Solid Carbide

Product Description

The SGS 51013 is a jobber-length drill bit ground from solid micrograin carbide and finished bright with no coating. It measures 0.1850 inches in diameter, which corresponds to wire gauge size 13 and 4.70 millimeters. The 118-degree faceted drill point is web-thinned for easier entry and reduced thrust in a wide range of materials. Overall length is 2.75 inches with a 1.625-inch spiral flute and a straight cylindrical shank. Right-hand cut with a regular spiral and two flutes, this bit suits precision drilling operations where carbide hardness and dimensional accuracy are required. Diameter tolerance runs from -0.0005 to 0.0000 inches.

This bit is intended for use on drill presses, CNC machining centers, and manual lathes in machine shops, fabrication facilities, and industrial maintenance settings. It is well suited for drilling ferrous and non-ferrous metals, plastics, and composites where solid carbide outperforms high-speed steel in tool life and cut quality. The straight shank fits standard three-jaw chucks and collet systems without adapters. Series 101 designation follows DIN 338 standards, making it a recognized jobber-length form factor for production and toolroom environments.

Key Features

• Right-hand cut, regular spiral, two-flute design for efficient chip evacuation
• Diameter tolerance of -0.0005 to 0.0000 inches for precision fitment
• Conforms to DIN 338 jobber-length standard, Series 101

Compatibility

Designed as a DIN 338 Series 101 jobber-length drill bit compatible with standard straight-shank chucks and collet holders sized for a 0.1850-inch shank diameter.

Installation Notes

Installation and use should be performed by machinists or qualified tradespeople familiar with rotating cutting tools. Secure the straight shank fully in the chuck or collet before operation and verify runout before drilling. Solid carbide bits are brittle compared to high-speed steel - avoid side loading, interrupted cuts without proper feed adjustment, or use in hand drills where lateral movement can cause fracture. Always follow the machine manufacturer's recommended speeds and feeds for carbide tooling in the workpiece material being drilled.
