Kennametal 1913576 Solid Carbide Jobber Drill 6.50 Mm

Product Description

The KENNAMETAL 1913576 is a solid carbide jobber-length drill designed for high-performance hole-making in demanding production environments. It features a 6.50 mm (0.2559 inch) cutting diameter, a 140-degree split point for reduced thrust and accurate self-centering, and a TiAlN coating that extends tool life under high heat and abrasive conditions. Overall length is 91.00 mm (3.5827 inches) with a flute length of 53.00 mm (2.0866 inches). A web-thinned, parallel web geometry reduces cutting forces at entry. This drill is installed and operated by machinists and tool-and-die professionals on CNC machining centers and manual drill presses.

This jobber drill is suited for drilling steel, stainless steel, cast iron, aluminum, and other non-ferrous materials in both job-shop and production settings. The through-coolant capability makes it well-matched to deep-hole operations where chip evacuation and heat management are critical. The straight cylindrical shank with an 8 mm (0.3150 inch) shank diameter fits standard ER and straight-bore toolholders common in CNC milling and drilling setups. Maximum drilling depth is 43.00 mm (1.6929 inches).

Key Features

• 6.50 mm cutting diameter with diameter tolerance of +0.006 to +0.021 mm for consistent hole sizing
• TiAlN coating improves heat resistance and extends tool life in ferrous and stainless applications
• 140-degree point angle with web thinning reduces entry thrust and improves centering
• Through-coolant design supports chip flushing and thermal control in deeper holes
• Right-hand cut, regular spiral flute geometry compatible with standard CNC programming
• Conforms to DIN 6537L specification for dimensional interchangeability

Compatibility

Designed as an OEM-specification jobber drill per DIN 6537L, compatible with standard straight-bore and ER-style toolholders accepting an 8 mm shank diameter. Suitable for use on CNC machining centers and drill presses configured for 6.50 mm tooling.

Installation Notes

Installation should be performed by a qualified machinist following the toolholder manufacturer's clamping torque guidelines. Confirm the spindle and toolholder are fully de-energized and stationary before loading or removing the drill. Through-coolant passages must be clear and supply pressure must be compatible with the machine tool before operation. Follow applicable ANSI and shop safety standards for rotating cutting tools.
