Kennametal 4150206 Screw Machine Drill Bit Solid Carbide

Product Description

The KENNAMETAL 4150206 is a screw machine length drill bit engineered for high-performance drilling in metalworking and machining applications. Built from solid carbide, it delivers the rigidity and wear resistance needed for demanding production environments. The bit features a TiN (Titanium Nitride) coating applied at the tip, which reduces friction and extends tool life during repeated drilling cycles. With a 140-degree split point and a standard two-flute regular spiral configuration, the 4150206 provides accurate entry, reduced thrust, and efficient chip evacuation. This is a right-hand cutting tool with a straight shank, part of the Kennametal B041A series. It is installed and operated by machinists, tool and die technicians, and maintenance tradespeople working with machining centers, drill presses, or CNC equipment.

The 4150206 is suited for screw machine operations and short-hole drilling applications where a stub-length drill reduces deflection and improves hole accuracy. The solid carbide construction makes it appropriate for use in harder workpiece materials where high-speed steel tooling would wear prematurely. The straight shank allows it to seat in standard drill chucks and collet-style toolholders commonly found in both manual and CNC machining setups. This bit is packaged individually and is a direct single-piece purchase.

Key Features

• Solid carbide construction provides superior hardness and wear resistance compared to HSS tooling
• TiN coating at the tip reduces friction and heat buildup during drilling
• 140-degree standard point angle minimizes walking and reduces entry thrust
• Two-flute regular spiral design promotes efficient chip removal from the hole
• Right-hand cutting direction with straight shank for compatibility with standard toolholding
• Screw machine (stub) length reduces overhang for improved rigidity and hole accuracy

Compatibility

Designed as an OEM-style replacement or direct tooling selection for screw machine and short-hole drilling applications using standard straight-shank drill chucks and collet toolholders. No specific compatible machine models were stated in the product data.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully powered down and at a complete stop before changing tooling. Seat the straight shank fully and evenly in the chuck or collet before tightening to the toolholder manufacturer's recommended procedure. Do not exceed the drill's rated cutting parameters for the workpiece material, as solid carbide is brittle and susceptible to breakage under shock loading or improper feed rates.
