Kennametal 1235736 Solid Carbide Jobber Drill Wire 19

Product Description

The KENNAMETAL 1235736 is a solid carbide jobber-length drill bit sized to wire gauge 19 (0.1660 inches decimal), designed for precision hole-making in demanding materials. The 130-degree point angle and web-thinned geometry reduce entry force and improve centering on hard or abrasive workpieces. A TiAlN coating provides thermal resistance and extended tool life at elevated cutting speeds. Three regular-spiral flutes promote efficient chip evacuation. With an overall length of 2.9100 inches and a 3/16-inch straight cylindrical shank, this drill is suited for CNC machining centers and manual drill presses where tight diameter tolerances are required. It conforms to DIN 6537L.

This drill is intended for machining cast iron, aluminum and non-ferrous metals, and high-temperature alloys. It is a common choice in aerospace, automotive, and general precision machining applications where consistent hole quality and dimensional accuracy are critical. The 1.3800-inch flute length supports a maximum drilling depth of 1.1300 inches per pass. Installation and use are performed by machinists and CNC operators working in production or job-shop environments.

Key Features

• Solid carbide construction at material grade K10 for rigidity and wear resistance in hard workpiece materials
• TiAlN coating for elevated thermal protection and extended tool life at higher surface footage
• 130-degree point angle with web thinning reduces thrust and improves self-centering on entry
• Three-flute design improves chip evacuation and surface finish in non-ferrous and high-temp alloy cuts
• Diameter tolerance held to +0.0002 to +0.0006 inches for consistent fit and finish in close-tolerance work
• Conforms to DIN 6537L specification for predictable geometry and interchangeability

Compatibility

Designed for use in cast iron, aluminum and non-ferrous metals, and high-temperature alloys as stated by the manufacturer. The 3/16-inch straight cylindrical shank fits standard drill chucks and collet holders accepting that shank diameter.

Installation Notes

This drill is installed by machinists in CNC machining centers or manual drill presses equipped with a compatible chuck or collet sized for a 3/16-inch straight shank. Ensure the machine spindle is fully stopped and locked out before changing tooling. Verify runout at the shank before cutting to avoid premature edge failure, which is especially critical with solid carbide tooling. Do not exceed the maximum drilling depth of 1.1300 inches per pass without retracting to clear chips.
