Hertel C.E96.S60-2 Screw Machine Drill Bit Set 60 Pc

Product Description

The HERTEL C.E96.S60-2 is a 60-piece screw machine length drill bit set designed for metalworking and multipurpose drilling applications. Each bit is manufactured from high-speed steel with an oxide finish and features a 135-degree split-point tip for fast, self-centering starts without a center punch. The straight shank design is compatible with standard drill chucks. The short flute length of screw machine drills provides added rigidity over jobber-length bits, making this set a practical choice for production shops, machine operators, and maintenance technicians who work in tight clearances or require reduced deflection in harder materials.

This set covers wire gauge sizes 1 through 60, providing a full range for tapping, reaming prep, and close-tolerance hole work in metal, plastics, and composite materials. The set is well suited for general metalworking environments including machine shops, fabrication facilities, and industrial maintenance operations. The heavy-duty designation reflects the HSS construction and oxide coating, which offers moderate lubricity and corrosion resistance during cutting. All 60 drills store in an included metal index case for organized access on the bench or in the field.

Key Features

• 135-degree split-point tip starts on contact and reduces walking on flat or curved metal surfaces
• High-speed steel construction handles steel, cast iron, aluminum, and most non-ferrous metals
• Oxide finish provides a low-friction surface and light corrosion protection
• Screw machine length (stub) flutes add rigidity and reduce deflection compared to jobber-length drills
• Straight shank fits standard keyed and keyless drill chucks without adapters
• Metal index case organizes all 60 wire-gauge sizes from 1 to 60 for fast selection

Compatibility

Designed for use with standard straight-shank drill chucks on bench drills, drill presses, CNC machining centers, and handheld power drills used in inch-system metalworking applications.

Installation Notes

Installation is performed by machinists, toolroom technicians, or maintenance mechanics familiar with drilling operations. Secure the workpiece firmly before drilling and confirm chuck engagement before starting the spindle. Use cutting fluid or coolant where required by the workpiece material to extend bit life, noting that this set does not support coolant-through delivery. Inspect bits for chipping or wear before each use and replace any damaged drills to maintain hole quality and prevent breakage.
