Precision Twist Drill 5995608 R41 60-Piece Screw Machine Length HSS Drill Bit Set

The Precision Twist Drill 5995608 is a professional-grade 60-piece Screw Machine Length Drill Bit Set from the Series R41 line. Engineered for high-accuracy drilling in machining, manufacturing, and industrial environments, this comprehensive set delivers consistent performance across a wide range of materials and drilling applications.

Screw machine length (stub length) drill bits feature a shorter overall length than standard jobber drills, providing increased rigidity and reduced deflection — ideal for use in drill presses, CNC machines, turret lathes, and screw machines where precision and stability are critical.

Key Features:

• 60-piece set covering a broad range of fractional, wire gauge, or letter sizes
• Series R41 screw machine (stub) length design for maximum rigidity and accuracy
• 118° conventional point angle for versatile general-purpose drilling
• High Speed Steel (HSS) construction for durability and heat resistance
• Bright/Uncoated finish — ideal for drilling softer materials including aluminum, wood, and plastics
• Straight shank compatible with standard drill chucks
• Right-hand cutting direction for standard drilling operations

The Precision Twist Drill brand, a product line of Dormer Pramet, has been trusted in precision engineering environments since 1952. The R41 Series set is an excellent choice for shops seeking a reliable, full-range stub-length drill index for production or maintenance use.
