Kennametal 4149187 Jobber Drill Size 27 Solid Carbide

Product Description

The KENNAMETAL 4149187 is a solid carbide jobber-length drill bit sized to wire gauge number 27 (0.1440 inches decimal equivalent). It features a 140-degree point angle ground to a standard point type, making it well suited for entry through harder materials without excessive thrust. A multilayer TiAlN coating reduces heat buildup at the cutting edge and extends tool life in demanding applications. The two-flute regular spiral design promotes chip evacuation, and the through-coolant capability allows direct delivery of cutting fluid to the tip. Overall length is 2.5984 inches (66.00 mm) with a flute length of 1.1024 inches (28.00 mm).

This drill bit is designed for precision hole-making in steel, stainless steel, cast iron, aluminum, and other non-ferrous materials. It is appropriate for CNC machining centers, production drilling, and manual drill press operations where consistent hole quality and tight diameter tolerance are required. The straight cylindrical shank diameter of 0.6875 inches fits standard collet chucks and drill holders. Maximum drilling depth is 0.9055 inches (23.00 mm). The 5xD flute-to-diameter ratio and tapered web configuration support stable cutting in short-to-medium depth holes across a wide range of workpiece materials.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive workpiece materials
• Multilayer TiAlN coating reduces friction and thermal load at the cutting edge
• 140-degree point angle minimizes walking and reduces thrust force on entry
• Through-coolant design delivers cutting fluid directly to the drill tip for deep-hole thermal management
• Right-hand cutting, regular spiral flute for reliable chip evacuation
• Manufactured to DIN 6537K specification for consistent dimensional accuracy

Compatibility

Designed as an OEM-specification replacement or direct-use drill for CNC and manual machining applications requiring a wire gauge number 27 diameter drill in solid carbide with a straight cylindrical shank. Compatible with workpiece materials including steel, stainless steel, cast iron, aluminum, and non-ferrous alloys as specified by the manufacturer.

Installation Notes

Installation and use should be performed by qualified machinists or tooling technicians familiar with cutting tool setup procedures. Ensure the machine spindle and collet or chuck are powered down and fully stopped before loading or removing the drill. Verify shank runout and chuck engagement before beginning a drilling cycle. Use manufacturer-recommended coolant flow rates when using the through-coolant feature to prevent thermal damage to the carbide substrate.
