Kennametal 1913532 Screw Machine Drill Bit 8.50mm Carbide

Product Description

The KENNAMETAL 1913532 is a screw machine length drill bit engineered for high-performance drilling in ferrous and cast iron materials. Built from solid carbide and coated with a multilayer TiAlN finish, this bit is designed to handle demanding production environments where tool life and dimensional accuracy are critical. It measures 8.50 mm in diameter with an overall length of 89.00 mm (3.5039 inches) and features a 140-degree split point for accurate self-centering entry. The straight cylindrical shank at 10.00 mm diameter fits standard drill chucks and toolholders. Coolant-through capability supports high-speed applications where heat management is essential. This bit is specified to DIN 6537K and is intended for installation and use by skilled machinists and tool and die technicians.

This drill bit is suited for production machining operations involving cast iron and steel workpieces. Its screw machine length body provides added rigidity compared to jobber-length bits, making it a preferred choice for CNC machining centers, drill presses, and screw machines running repetitive hole cycles. The web-thinned, parallel-web construction reduces thrust load at entry. Maximum drilling depth is 35.00 mm (1.378 inches), and the flute length is 47.00 mm (1.8504 inches). The TiAlN multilayer coating extends cutting life in abrasive materials and at elevated cutting temperatures common in production environments.

Key Features

• Solid carbide construction for superior rigidity and wear resistance in hard materials
• Multilayer TiAlN coating extends tool life in cast iron and steel applications
• 140-degree point angle with web thinning reduces entry thrust and improves centering
• Coolant-through design supports high-speed and deep-hole drilling cycles
• Straight cylindrical shank at 10.00 mm diameter for standard toolholder compatibility
• Manufactured to DIN 6537K specification for consistent dimensional tolerancing

Compatibility

Designed as an OEM-style screw machine length drill bit for use in CNC machining centers, drill presses, and screw machines requiring a 10.00 mm straight shank. Primary workpiece materials are cast iron and steel as specified by the manufacturer.

Installation Notes

Installation should be performed by a qualified machinist following standard toolholding procedures. Ensure the machine spindle is fully stopped and locked out before inserting or removing the bit from the chuck or collet. Verify that the shank is fully seated and secured to the recommended clamping torque for the toolholder in use. Use appropriate cutting fluid or coolant-through supply when drilling steel or cast iron to prevent premature coating degradation.
