Kennametal 4150733 Solid Carbide Jobber Drill 9.60mm

Product Description

The KENNAMETAL 4150733 is a solid carbide jobber-length twist drill designed for high-performance hole-making in demanding materials. It measures 9.60 mm in diameter with a 140-degree point angle and a multilayer TiAlN coating that extends tool life under high heat and abrasion. The drill has an overall length of 103.00 mm (4.06 inches) and a flute length of 61.00 mm (2.40 inches). The straight cylindrical shank seats into standard drill chucks and collet holders without modification. Right-hand cutting direction and a regular spiral flute geometry move chips efficiently out of the hole. This drill is suited for production environments where carbide rigidity and coating performance justify the investment over high-speed steel alternatives.

This jobber drill is intended for use in metalworking applications across steel, stainless steel, cast iron, and aluminum and non-ferrous materials. The 5xD flute-to-diameter ratio and 140-degree split-style point make it a practical choice for through-hole and blind-hole drilling in CNC machining centers and drill presses running at appropriate feeds and speeds for carbide tooling. The DIN 6537K specification governs dimensional standards. Maximum drilling depth is 49.00 mm (1.93 inches). No coolant-through feature is present, so external or flood coolant should be directed at the cutting zone when drilling deep features or hard alloys.

Key Features

• Solid carbide construction provides rigidity and wear resistance beyond high-speed steel in hard and abrasive workpiece materials
• Multilayer TiAlN coating resists heat buildup and oxidation, extending cutting life in steel and stainless steel
• 140-degree point angle reduces thrust and improves centering on entry compared to conventional 118-degree geometry
• Regular spiral flute with tapered web configuration promotes chip evacuation in both ferrous and non-ferrous materials
• Straight cylindrical shank with 10 mm shank diameter fits standard ER collets and Jacobs-style chucks
• Conforms to DIN 6537K dimensional specification for consistent interchangeability

Compatibility

Designed as a DIN 6537K standard solid carbide jobber drill suitable for use in CNC machining centers, knee mills, and drill presses equipped with collet chucks or Jacobs-style chucks accepting a 10 mm straight shank. Compatible workpiece materials include steel, stainless steel, cast iron, and aluminum and non-ferrous alloys as specified by the manufacturer.

Installation Notes

Machinist or CNC operator installation. Verify spindle runout is within acceptable tolerance before seating carbide tooling, as carbide is more brittle than high-speed steel and sensitive to lateral loading from excessive runout. Power down and lock out the machine before changing tooling. Do not use this drill in a hammer or impact-mode setting. Apply external flood or mist coolant directed at the cutting zone when drilling deep features or hard alloys, as this drill does not have coolant-through capability.
