Kennametal 4151736 Taper Length Drill Bit 1.5 Mm

Product Description

The KENNAMETAL 4151736 is a solid carbide taper length drill bit engineered for precision drilling in demanding machining applications. Built to DIN 6537K standards, it features a 140-degree point angle and a multilayer TiAlN coating in material grade KC7325. The coating provides thermal resistance and extended tool life when cutting ferrous and non-ferrous materials at elevated speeds. At 1.5 mm in diameter with a straight cylindrical shank of 4.0 mm, this bit is suited for CNC machining centers and manual drill presses where consistent hole quality and tight tolerances are required. Machinists and tool and die professionals are the primary installers.

The 4151736 is used in precision metalworking environments including aerospace, automotive, and general manufacturing. The spiral flute geometry with a right-hand cut promotes chip evacuation during through-hole and blind-hole operations. The 8xD flute-to-diameter ratio supports deeper drilling with reduced deflection at this small diameter. Coolant-through capability makes it well suited for high-speed applications where heat management is critical. It fits standard straight-shank tool holders and collet chucks compatible with a 4.0 mm shank diameter.

Key Features

• Solid carbide construction in material grade KC7325 for rigidity and wear resistance
• Multilayer TiAlN coating for thermal protection and extended tool life
• 140-degree standard point angle reduces thrust force at entry
• Coolant-through design supports high-speed and deep-hole drilling
• Right-hand spiral flute with tapered web configuration for efficient chip removal
• Meets DIN 6537K specification for consistent dimensional standards

Compatibility

Designed as an OEM-style replacement for solid carbide taper length drill bits in the KENNAMETAL B053A-CPG series, compatible with straight-shank collet chucks and tool holders accepting a 4.0 mm shank diameter.

Installation Notes

Installation and use should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and locked out before changing or inspecting tooling. Secure the straight shank in a properly sized collet or chuck to the manufacturer-specified clamping torque range for the holder type in use. Verify coolant-through passages are clear before operation if using internal coolant delivery.
