Hertel 83246330 Straight-flute Drill Bit No. 34 Carbide

Product Description

The HERTEL 83246330 is a straight-flute drill bit ground from solid C2 carbide and sized to wire gauge No. 34, equal to 0.1110 inches in diameter. It carries a 140-degree notched point with web thinning, a geometry that reduces thrust force and improves centering on entry. The bright, uncoated finish keeps tolerances tight and allows visual inspection of the cutting edge after each use. With a diameter tolerance of +0.0000 to -0.0005 inches, it holds the close fits required in precision drilling operations. Right-hand cutting direction, two flutes, and no coolant-through design make this a straightforward tool for solid-material applications in machining and fabrication environments.

This bit is suited to drilling chrome alloy, heat-treated alloy, nickel alloy, stainless steel, carbon steel, and titanium alloy workpieces. The C2 carbide grade handles the hardness and abrasiveness of these materials better than high-speed steel, making it a practical choice for production shops, tool rooms, and maintenance machinists working with ferrous and exotic alloys. The straight-flute design is particularly effective in materials that tend to grab or chatter with conventional spiral flutes.

Key Features

• Solid C2 carbide construction for durability in hard and abrasive workpiece materials
• 140-degree notched point with web thinning reduces entry thrust and improves hole location accuracy
• Wire gauge No. 34 size at 0.1110 inches with a tight tolerance of +0.0000 to -0.0005 inches
• Straight-flute geometry suits materials prone to chatter or grabbing with spiral flutes
• Bright, uncoated finish allows straightforward edge inspection and regrinding
• Right-hand cutting, two-flute design compatible with standard drill presses and CNC machining centers

Compatibility

Rated for primary and secondary workpiece materials including chrome alloy, heat-treated alloy, nickel alloy, stainless steel, steel, and titanium alloy. Compatible with any standard drill press, CNC machining center, or hand-held power tool chuck accepting a 0.1110-inch shank diameter.

Installation Notes

This bit is installed and serviced by machinists and tool room technicians. Secure the shank firmly in a collet or drill chuck before operation and verify runout is within acceptable limits for the application. Do not exceed the recommended spindle speed for the workpiece material and bit diameter, as carbide is brittle and susceptible to chipping under excessive load or vibration. Inspect the cutting edge for chipping or wear before each use; a damaged carbide edge should be reground or the bit replaced before continuing work.
