Kennametal 4151800 Jobber Drill 41 Wire 0.0960 in Carbide

Product Description

The KENNAMETAL 4151800 is a solid carbide jobber-length drill bit sized to wire gauge 41 (0.0960 inches) and engineered for high-performance drilling in demanding production environments. The bit features a 140-degree split-point geometry that self-centers on contact and reduces thrust load, paired with a multilayer TiAlN coating for extended tool life under heat. Overall length is 2.2835 inches (58.00 mm), with a flute length of 0.8661 inches (22.00 mm) and a straight cylindrical shank diameter of 0.0781 inches. Right-hand spiral flutes with a regular helix evacuate chips efficiently during through-hole and blind-hole operations. Licensed machinists, tool-and-die technicians, and production drilling specialists are the primary users.

This drill is suited for precision small-diameter hole applications across a range of workpiece materials including steel, stainless steel, cast iron, aluminum, and other non-ferrous metals. The 5xD flute-to-diameter ratio and tapered web configuration support consistent performance in CNC machining centers, drill presses, and manual machines where repeatable hole quality is required. The DIN 6537K specification governs dimensional standards for this bit. Coolant-through capability is not available on this model.

Key Features

• Wire gauge 41 diameter (0.0960 inches) with tight tolerance of -0.0006 to 0.0000 inches for precise hole sizing
• 140-degree standard point angle for reduced thrust and self-centering entry
• Solid carbide construction with multilayer TiAlN coating for heat resistance and extended tool life
• Regular spiral flute geometry with tapered web for efficient chip evacuation
• Right-hand cutting direction, straight shank - compatible with standard drill chucks and collets
• Manufactured to DIN 6537K specification for dimensional consistency

Compatibility

Designed as an OEM-specification solid carbide jobber drill for use in standard drill chucks, ER collet systems, and toolholders accepting a 0.0781-inch straight cylindrical shank. Suitable for steel, stainless steel, cast iron, aluminum, and non-ferrous workpiece materials as noted in the product specification.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the machine powered down and locked out per applicable safety procedures. Ensure the shank is fully seated and the chuck or collet is torqued to the toolholder manufacturer specification before operation. Solid carbide tooling is brittle - avoid side loading, interrupted cuts without appropriate feed reduction, and dropping or impact against hard surfaces. Verify spindle runout is within acceptable limits before use to prevent premature tool breakage at this small diameter.
