Hertel 74132036 Screw Machine Drill Bit Size 5 Cobalt

Product Description

The HERTEL 74132036 is a screw machine length drill bit engineered for high-performance drilling in metal fabrication, machining, and production environments. Built from cobalt tool steel with a TiAlN coating, it handles elevated cutting temperatures without sacrificing edge integrity. The 135-degree split point reduces walking and lowers thrust requirements, allowing cleaner entry into ferrous and non-ferrous materials alike. At 2.375 inches overall length, the stub-style body provides rigidity that standard jobber-length bits cannot match in short-reach or fixture-guided setups. This bit is sized to wire gauge 5, corresponding to a decimal diameter of 0.2055 inches.

This drill bit is suited for CNC machining centers, drill presses, and manual machine setups where hole tolerances and tool life are priorities. The screw machine length profile is a standard choice in production shops drilling repetitive holes in steel, stainless, cast iron, and hard alloys. The straight-cylindrical shank seats cleanly in standard drill chucks and collets. A web-thinned, parallel-web construction reduces cutting resistance at the chisel edge, improving chip evacuation in deeper holes.

Key Features

• Cobalt tool steel construction resists heat buildup during aggressive metal cutting
• TiAlN coating extends tool life in high-temperature and dry-cutting applications
• 135-degree split point reduces thrust and prevents walking on entry
• Web-thinned parallel web improves chip flow and lowers cutting torque
• Screw machine length body provides added rigidity over standard jobber-length bits
• Straight-cylindrical shank fits standard drill chucks and collets without adapters

Compatibility

Designed as a direct-fit replacement for wire gauge size 5 screw machine length drill bits used in standard drill chucks and collets accepting a straight-cylindrical shank in the 0.2055-inch diameter range.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Secure the shank fully in the chuck or collet and verify runout before beginning a cut. Follow applicable shop safety protocols and machine guarding requirements. Do not exceed the rated speed range for cobalt bits in the material being drilled, and use appropriate cutting fluid where the application calls for it.
