Sgs 64841 Carbide Jobber Drill Bit 7.10mm 124 Deg Tib2

Product Description

The SGS 64841 is a solid carbide jobber length drill bit designed for high-performance drilling in demanding industrial and machining applications. It measures 7.10 mm (0.2795 inches) in diameter with a 124-degree notched drill point angle and features a Titanium Diboride (TiB2) coating for enhanced wear resistance and reduced friction. The bit runs a right-hand cut with a three-flute regular spiral configuration, which improves chip evacuation and supports higher feed rates compared to standard two-flute designs. Overall length is 91.00 mm (3.58 inches). This bit is suited for machinists, toolroom technicians, and production drilling professionals working with precision tolerances.

The SGS 64841 Series 131N is built for high-performance drilling in ferrous and non-ferrous materials where dimensional accuracy and tool life are critical. Its 5xD flute-to-diameter ratio and 43.00 mm maximum drilling depth make it appropriate for moderate-depth hole applications on CNC machining centers, drill presses, and manual mills. The straight cylindrical shank seats securely in standard collets and drill chucks. This bit is a solid choice for production environments, job shops, and tool cribs requiring consistent, repeatable hole quality at tight tolerances.

Key Features

• Solid carbide construction delivers superior hardness and rigidity compared to HSS alternatives
• Titanium Diboride (TiB2) coating reduces friction and extends tool life in abrasive materials
• 124-degree notched point angle improves self-centering and reduces thrust force at entry
• Three-flute spiral design enhances chip evacuation and supports higher feed rates
• Straight cylindrical shank with 8.00 mm shank diameter for compatibility with standard collets and chucks
• Diameter tolerance of +0.006 to +0.021 mm ensures consistent, tight-tolerance hole sizing

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide drill bit for CNC machining centers, drill presses, and milling machines accepting straight cylindrical shank tooling in the 7.00 to 8.00 mm drill bit size range.

Installation Notes

Installation and use should be performed by a qualified machinist or toolroom technician familiar with carbide tooling. Ensure the machine spindle and collet or chuck are clean and free of debris before seating the shank to prevent runout. Carbide is brittle compared to HSS - avoid lateral loading, side pressure, or impact that can cause chipping or fracture. Always confirm correct spindle speed and feed rate for the workpiece material before beginning the cut.
