Kennametal 1191614 Solid Carbide Die Drill Bit 0.3150 in

Product Description

The KENNAMETAL 1191614 is a solid carbide straight-flute die drill bit engineered for precision hole-making in cast iron and non-ferrous metals. Part of the B411 series, it features a 130-degree split point with web thinning to reduce thrust and improve centering at entry. The bright (uncoated) carbide construction delivers hardness and heat resistance suitable for demanding production environments. Internal coolant-through capability via a round coolant hole supports chip evacuation and extends tool life in deeper drilling applications. This bit is sized at 0.3150 inches (8.00 mm) in diameter and conforms to DIN 6537L standards.

This drill bit is suited for machining operations in tool-and-die, mold making, and precision component manufacturing. It performs in both manual and CNC setups where tight hole tolerances and clean entry geometry are required. The right-hand cutting direction and two-flute straight configuration make it a practical choice for machinists working with cast iron, aluminum, copper, and similar non-ferrous workpiece materials. Maximum drilling depth reaches 1.69 inches (43.00 mm), making it appropriate for moderate-depth bores in die and mold work.

Key Features

• Straight-flute geometry optimized for die and mold drilling applications
• 130-degree split point with web thinning for reduced entry thrust and improved self-centering
• Coolant-through design with round coolant hole supports chip flushing at depth
• Solid carbide construction provides rigidity and wear resistance in abrasive workpiece materials
• Bright finish with no coating — suited for applications where coating adhesion or contamination is a concern
• Conforms to DIN 6537L specification for consistent dimensional accuracy

Compatibility

Designed as a replacement or production-use die drill bit for machining operations involving cast iron and non-ferrous metals where an 8.00 mm straight-flute carbide drill conforming to DIN 6537L is specified.

Installation Notes

This tool is installed and operated by trained machinists or toolroom technicians. Secure the shank fully in a collet or drill chuck rated for the shank diameter before use. Verify spindle speed and feed rate are appropriate for the workpiece material and drill diameter before engaging the cut. Engage coolant flow before drilling when using the through-coolant feature to prevent thermal shock to the carbide.
