Precision Twist Drill 5999974 R51 HSS Taper Length Drill Bit

Precision Twist Drill 5999974 is part of the R51 Series General Purpose Taper Length Drill line, a high-speed steel (HSS) drill bit engineered for applications requiring greater depth and reach than standard jobber-length drills.

Key Features:

• Series: R51 General Purpose Taper Length
• Material: High-Speed Steel (HSS) for excellent wear resistance in ferrous and non-ferrous materials
• Finish: Bright (uncoated) for smooth performance and cost-effective general-purpose use
• Point Angle: 118° conventional point — the industry-standard geometry for drilling metal, wood, and synthetics
• Flute Design: Standard two-flute spiral helical design for efficient chip evacuation
• Shank: Straight (plain round) shank sized to match the drill diameter
• Cutting Direction: Right-hand cut (clockwise rotation)
• Depth Capability: Up to 6x the drill diameter cutting depth
• Standard: Meets ANSI specifications

The R51 taper length design provides a longer flute and overall length compared to jobber drills, making it ideal for reaching deeper holes in production machining, metalworking, aerospace, and automotive applications. The 118° conventional point is the most widely accepted standard for versatile, multi-material drilling.
