Precision Twist Drill 5995635 Drill Bit Set 29 Pc

Product Description

The PRECISION TWIST DRILL 5995635 is a 29-piece screw machine length drill bit set designed for metalworking and general-purpose drilling applications. Built from high speed steel (HSS) with a bright/uncoated finish, these bits cover a range from 1/16 inch to 1/2 inch in 1/64-inch step increments. The screw machine length geometry provides a shorter, more rigid profile than jobber-length bits, reducing deflection and improving accuracy in drill press and CNC lathe work. The 118-degree standard point angle suits a wide range of ferrous and non-ferrous metals. All 29 bits are organized in a metal storage case. The set meets ANSI specifications and uses straight shanks throughout.

This set is suited for machine shops, maintenance technicians, and fabrication professionals who need a complete fractional inch drill index in a compact format. Screw machine length bits are commonly used in turret lathes, drill presses, and benchtop machines where reduced overhang is critical to hole quality. The 1/16-inch to 1/2-inch coverage handles most standard fastener clearance and tap drill requirements encountered in everyday metalworking and multipurpose drilling tasks.

Key Features

• 29-piece set covering 1/16 inch to 1/2 inch in 1/64-inch increments
• Screw machine (stub) length for increased rigidity and reduced deflection
• High speed steel construction for general-purpose metalworking durability
• 118-degree standard point angle compatible with a broad range of materials
• Straight shank fits standard drill chucks without adapters
• Bright/uncoated finish — no coating buildup to affect hole tolerance
• Metal index case keeps bits organized and protected

Compatibility

Designed as a general-purpose fractional inch drill bit set for use in drill presses, turret lathes, CNC machines, and hand-held drills equipped with standard straight-shank chucks. Conforms to ANSI standards for screw machine length drill bits.

Installation Notes

Install and remove bits only when the machine is fully powered down and the chuck has stopped rotating. Secure the straight shank firmly in the chuck to the full depth of the chuck jaws to prevent slipping under load. Use cutting fluid or coolant appropriate for the workpiece material to extend bit life, even though these bits do not have through-coolant capability. Inspect each bit for chipping or wear before use, and replace any bit that shows visible damage to avoid inaccurate holes or breakage.
