Kennametal 4150202 Screw Machine Drill Bit Solid Carbide

Product Description

The KENNAMETAL 4150202 is a screw machine length drill bit engineered for high-performance drilling in demanding shop and production environments. Built from solid carbide and finished with a TiN (Tip) coating, this bit delivers extended tool life and reduced wear at the cutting edge. It features a 140-degree drill point angle, a two-flute regular spiral configuration, and a straight shank for secure chuck retention. The shortened screw machine length provides increased rigidity compared to jobber-length drills, making it well suited for CNC machining centers, drill presses, and manual machine operations where deflection control and hole accuracy matter. Installation and operation are performed by machinists and tool-room professionals.

This drill bit is designed for use in production drilling applications across metalworking, fabrication, and machine shop settings. The solid carbide construction makes it appropriate for harder workpiece materials where high-speed steel tooling would wear prematurely. The TiN tip coating reduces friction at the point of entry, improving chip evacuation and extending tool life in repetitive drilling cycles. It is sold individually and is part of the KENNAMETAL B041A series.

Key Features

• Solid carbide construction for superior hardness and wear resistance in production drilling
• TiN (Tip) coating reduces cutting friction and extends tool life at the drill point
• 140-degree drill point angle promotes self-centering and reduces thrust force
• Two-flute regular spiral design supports efficient chip evacuation
• Straight shank compatible with standard drill chucks and collet holders
• Screw machine length provides added rigidity and reduced deflection over jobber-length bits

Compatibility

Designed as an OEM-style replacement screw machine length drill bit for use in standard straight-shank drill chucks, collet holders, and compatible CNC or manual machine tool spindles.

Installation Notes

This drill bit is installed and operated by machinists and tool-room technicians. Ensure the machine spindle is fully de-energized and at rest before inserting or removing tooling. Verify chuck or collet runout is within acceptable tolerance before use, as excessive runout accelerates carbide tool wear and can cause premature breakage. Follow machine manufacturer guidelines and applicable shop safety procedures when operating carbide tooling at rated speeds and feeds.
