Kennametal 1913496 Carbide Drill Bit 0.4134 Inch 140 Degree

Product Description

The KENNAMETAL 1913496 is a solid carbide screw machine length drill bit designed for high-productivity drilling in ferrous metals and cast iron. It measures 10.50 mm (0.4134 inches) in diameter with a 140-degree split point and carries a multilayer TiAlN coating that extends tool life in demanding cutting conditions. The right-hand spiral flute geometry evacuates chips efficiently during through-hole and blind-hole operations. At 102.00 mm (4.016 inches) overall length with a 55.00 mm (2.165 inches) flute length, it fits standard CNC machining centers, drill presses, and screw machines. Machinists, toolroom technicians, and production floor operators use this bit in high-volume applications where consistent hole quality and dimensional accuracy are required.

This drill bit is suited for drilling cast iron and steel in production machining environments, including automated CNC drilling cycles and manual drill press setups. Its screw machine length profile provides added rigidity compared to jobber-length bits, reducing deflection in short-entry applications. The straight-cylindrical shank with a 12.00 mm (0.472 inches) diameter seats securely in standard drill chucks and collet holders. Maximum drilling depth is 40.00 mm (1.5748 inches). The web-thinned, parallel web configuration reduces thrust force at the cutting tip, which is especially beneficial when drilling harder steel grades and close-tolerance bores.

Key Features

• Solid carbide construction delivers rigidity and wear resistance in ferrous metal drilling
• Multilayer TiAlN coating improves heat resistance and extends cutting tool life at elevated spindle speeds
• 140-degree standard point angle with web thinning reduces entry thrust and improves centering accuracy
• Straight-cylindrical 12.00 mm shank is compatible with standard drill chucks and collet holders
• Screw machine length body increases stiffness and minimizes runout versus longer-series bits
• Conforms to DIN 6537K specification for consistent dimensional standards

Compatibility

The 1913496 belongs to Kennametal Series B966 and conforms to DIN 6537K specification. It is designed as an OEM-style replacement or direct-use solid carbide stub drill for CNC machining centers and drill presses requiring a 10.50 mm diameter, straight-shank carbide bit in the 0.4000 to 0.4500 inch (9.50 to 11.00 mm) drill bit size range.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the spindle is fully stopped and the machine is de-energized or in a safe lockout state before mounting or removing tooling. Seat the straight-cylindrical shank fully into the chuck or collet holder and verify runout before beginning a drilling cycle. This bit does not support coolant-through operation; apply flood or mist coolant externally at the cutting zone as required by the workpiece material and feed-speed parameters.
