Kennametal 4151803 Solid Carbide Jobber Drill Wire 38

Product Description

The KENNAMETAL 4151803 is a solid carbide jobber-length drill bit in wire gauge size 38, with a decimal diameter of 0.1015 inches. It features a 140-degree split-point geometry and a multilayer TiAlN coating for extended tool life in demanding applications. The straight cylindrical shank measures 0.4063 inches in diameter, and the overall length is 2.2835 inches (58.00 mm). Two regular spiral flutes clear chips efficiently along a flute length of 0.8661 inches. This bit is designed for right-hand cutting and conforms to DIN 6537K specifications. It is installed by machinists and tool-room technicians working in precision drilling operations on ferrous and non-ferrous materials.

This drill is suited for production and maintenance machining in industrial environments. Primary workpiece materials include steel, stainless steel, cast iron, and aluminum along with other non-ferrous alloys. The 5xD flute-to-diameter ratio and tapered web configuration support stable cutting at higher feed rates typical of CNC drilling centers and manual machining operations. It is packaged as a single unit and sold individually.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• Multilayer TiAlN coating reduces heat buildup and extends cutting life
• 140-degree point angle improves self-centering and reduces thrust in steel and stainless steel
• DIN 6537K specification ensures consistent dimensional standards
• Tapered web configuration with regular spiral flutes for effective chip evacuation
• Right-hand cutting with straight cylindrical shank for broad machine compatibility

Compatibility

Designed as an OEM-specification solid carbide jobber drill for use in CNC machining centers, drill presses, and similar equipment accepting a 0.4063-inch straight cylindrical shank. Suitable for drilling steel, stainless steel, cast iron, and aluminum or non-ferrous workpieces.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Power down and lock out the machine spindle before changing tooling. Ensure the shank is fully seated and securely clamped in the drill chuck or collet before operation. Verify spindle speed and feed rate are appropriate for the workpiece material and drill diameter before beginning the cut.
