Sgs 61082 Solid Carbide Jobber Drill Bit 0.1890 in Wire 12

Product Description

The SGS 61082 is a solid carbide jobber-length drill bit designed for precise, repeatable hole-making in demanding materials. It carries a wire gauge size of 12, equal to 0.1890 inches (4.80 mm), with a 118-degree four-facet point that promotes accurate starting and clean entry without walking. The bright, uncoated finish keeps the cutting edges sharp and visible for inspection. With an overall length of 3.3858 inches and a 2.0472-inch flute length, this bit is built to the DIN 338 standard and suits machinists, tool-and-die shops, and maintenance technicians who require tight-tolerance drilling in ferrous and non-ferrous stock.

The SGS 61082 is suited for general-purpose precision drilling in machine shops, fabrication environments, and MRO settings. The micrograin carbide substrate handles harder workpiece materials where high-speed steel bits fall short. It is appropriate for use in CNC machining centers, drill presses, and hand-held power tools with a suitable collet or chuck. The straight cylindrical shank accepts standard drill chucks without adapters. Typical applications fall within the 0.1500 to 0.2000 inch diameter range where wire-gauge sizing is the industry norm.

Key Features

• Solid micrograin carbide construction for extended tool life in hard or abrasive materials
• 118-degree four-facet point for self-centering entry and reduced thrust force
• Web-thinned tapered web reduces cutting resistance and improves chip evacuation
• Regular spiral two-flute design promotes consistent chip flow during through-hole drilling
• Bright, uncoated finish allows easy visual inspection of cutting edge condition
• Manufactured to DIN 338 standard for consistent dimensional accuracy

Compatibility

Designed as an OEM-style replacement or direct-fit tooling option for applications requiring a wire size 12 (0.1890 inch) jobber-length drill bit with a straight cylindrical shank in standard drill chucks and collet systems.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance technicians familiar with rotary cutting tool safety. Secure the straight shank fully in a properly sized chuck or collet before operating the machine, and confirm runout is within acceptable limits before drilling production parts. Always set spindle speed and feed rate according to the workpiece material and bit diameter before engaging the cut. Do not use this bit beyond its maximum drilling depth of 1.6142 inches in a single pass without retracting to clear chips.
