Kennametal 1913486 Screw Machine Drill Bit 7.80mm Carbide

Product Description

The KENNAMETAL 1913486 is a screw machine length solid carbide drill bit designed for high-performance drilling in metalworking applications. Built to DIN 6537K standards and coated with TiAlN for extended tool life, this bit delivers consistent performance in demanding production environments. It measures 7.80 mm in diameter with a 140-degree point angle optimized for accurate entry and reduced thrust. The overall length is 79.00 mm, making it well-suited for short-reach, rigid setups on CNC machines and drill presses. The KC7315 carbide grade and Dynapoint geometry make this a reliable choice for machinists and tool-and-die professionals running high-volume operations.

This drill bit is intended for use in ferrous metal applications, with primary workpiece materials listed as cast iron and steel. The screw machine length body provides greater rigidity compared to jobber-length bits, which is advantageous in tight-tolerance machining centers, turret lathes, and multi-spindle setups. The TiAlN coating supports higher cutting speeds and temperatures, reducing wear in production runs. It is suited for both manual machine shops and automated CNC drilling operations where consistent diameter tolerance and tool life are critical.

Key Features

• Solid carbide construction in KC7315 grade for hardness and wear resistance
• TiAlN coating extends tool life at elevated cutting temperatures
• 140-degree Dynapoint geometry reduces thrust and improves point accuracy
• Web-thinned parallel web configuration for easier penetration in hard materials
• DIN 6537K specification for dimensional consistency and interchangeability
• Right-hand cut with regular spiral flute for efficient chip evacuation

Compatibility

Designed as an OEM-style screw machine length drill bit for use in standard straight-shank drill chucks and collet holders accepting an 8.00 mm shank diameter, suitable for CNC machining centers, turret lathes, and multi-spindle drilling setups processing cast iron and steel workpieces.

Installation Notes

This bit should be installed by a qualified machinist or tooling technician familiar with carbide tooling handling and machine setup. Secure the straight shank in a properly sized collet or drill chuck before operation and verify runout before cutting. Carbide tooling is brittle and should never be subjected to impact loading or side forces beyond design parameters. Always follow machine manufacturer guidelines and applicable shop safety standards when setting feeds and speeds for carbide drill bits.
