Hertel 84578194 Jobber Drill No. 64 Wire 0.036 in 118 Deg Hss

Product Description

The HERTEL 84578194 is a No. 64 wire-size jobber-length drill bit ground from high speed steel (HSS) with a bright, uncoated finish. The bit measures 0.036 inches in diameter and carries a standard 118-degree split-point angle with a web-thinned, tapered web for clean entry and reduced thrust. Overall length is 1.5 inches with a 0.625-inch flute length and a straight, cylindrical shank. The two-flute regular spiral design evacuates chips efficiently in light-material drilling applications. This bit is a general-purpose tool suited to production, maintenance, and tool-room environments where fine wire-gauge holes are required.

Rated for aluminum and non-ferrous workpiece materials, the 84578194 is a practical choice for precision drilling in sheet metal, copper, brass, and similar soft alloys. The bright uncoated finish keeps the bit serviceable across a wide range of non-ferrous applications without added coating costs. The compact 1.5-inch overall length makes it well suited to close-quarters drilling in small fixtures, PCB work, and light assembly operations. No coolant-through capability; cutting fluid can be applied externally when needed.

Key Features

• No. 64 wire size, 0.036-inch diameter for fine-gauge hole requirements
• 118-degree standard point angle with web-thinned, tapered web for reduced entry thrust
• High speed steel construction for general-purpose durability across non-ferrous materials
• Bright, uncoated finish — no coating buildup to affect dimensional accuracy in tight-tolerance holes
• Regular spiral, two-flute design promotes efficient chip evacuation in short-flute geometry
• Straight cylindrical shank compatible with standard drill chucks and collets

Compatibility

Designed as a general-purpose jobber-length drill bit for use in standard drill presses, CNC machining centers, hand drills, and collet-equipped rotary tools accepting a 0.036-inch straight shank. Primary workpiece material rating is aluminum and non-ferrous alloys.

Installation Notes

Installation and use of small-diameter drill bits of this type is performed by machinists, maintenance technicians, and assembly professionals. Secure the shank fully in the chuck or collet before operation and verify runout is within acceptable limits, as bits at this diameter are sensitive to misalignment. Apply light, consistent feed pressure to avoid bit deflection or breakage — small wire-gauge bits are brittle under side load. External cutting fluid is recommended when drilling non-ferrous metals to extend tool life and improve hole finish.
