Kennametal 1191453 Solid Carbide Jobber Drill 11.80 Mm

Product Description

The KENNAMETAL 1191453 is a solid carbide jobber-length drill designed for precision hole-making in demanding materials. Built to DIN 6537L specification, it features a 130-degree point angle with web thinning for reduced thrust and improved chip evacuation at entry. The bright/uncoated carbide construction and K10 material grade make it well suited for high-speed drilling where heat resistance and edge retention are critical. Three regular spiral flutes provide efficient chip clearance across the full flute length of 71.00 mm. This drill is installed by machinists and maintenance technicians working in CNC machining centers and drill presses.

This jobber drill is engineered for use in cast iron, aluminum and non-ferrous metals, and high-temperature alloys. The straight cylindrical shank seats into standard ER collets, drill chucks, or toolholders with a matching 12 mm bore. Its 56.00 mm maximum drilling depth suits through-hole and blind-hole operations typical in production machining, job shop work, and maintenance repair environments where consistent hole geometry and tight tolerance are required.

Key Features

• Solid carbide K10 grade construction for extended tool life in abrasive and hard materials
• 130-degree point angle with web-thinned, tapered web for lower entry thrust
• Three-flute regular spiral design for improved chip evacuation versus two-flute styles
• Bright/uncoated finish compatible with cutting fluids and dry machining applications
• DIN 6537L specification ensures dimensional conformance for repeatable fitment
• Straight cylindrical shank fits standard toolholding systems without adapters

Compatibility

Designed as a DIN 6537L-compliant jobber drill for use in CNC machining centers, drill presses, and manual machines equipped with standard straight-shank toolholders or drill chucks accepting a 12 mm shank diameter. Primary workpiece materials include cast iron, aluminum and non-ferrous alloys, and high-temperature alloys.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the spindle is fully de-energized and the machine is locked out before loading or removing the drill. Seat the straight shank fully into the collet or chuck and verify runout before cutting. Solid carbide tooling is brittle and should not be used in machines with excessive spindle runout or in setups prone to lateral loading.
