Hertel 83246546 Straight-flute Drill Bit 0.1850 in Carbide

Product Description

The HERTEL 83246546 is a straight-flute drill bit machined from solid carbide grade C2, designed for drilling hard and abrasion-resistant materials in precision machining environments. It carries a wire gauge size of 13 with a decimal diameter of 0.1850 inches and a 140-degree notched point geometry that promotes self-centering and reduces thrust force at entry. Web thinning improves chip clearance and reduces cutting load. With a diameter tolerance of +0.0000 to -0.0005 inches, this bit holds tight dimensional accuracy suitable for close-tolerance hole work. It is used uncoated and runs without coolant-through capability. Machinists and toolroom professionals working in aerospace, industrial fabrication, and general machining rely on this geometry for consistent performance in tough alloy materials.

This drill bit is suited for production and toolroom applications where hard or exotic workpiece materials demand a rigid, low-flex cutting tool. Primary workpiece materials include chrome alloy, heat-treated alloy, nickel alloy, stainless steel, carbon steel, and titanium alloy. It operates with right-hand cutting direction and is appropriate for use in CNC machining centers, knee mills, and drill presses where spindle runout is controlled and feeds and speeds are dialed in for carbide tooling.

Key Features

• Solid carbide C2 grade construction provides rigidity and wear resistance in hard-material drilling
• 140-degree notched point geometry reduces entry thrust and improves self-centering
• Web-thinned design lowers cutting resistance and assists chip evacuation
• Tight diameter tolerance of +0.0000 to -0.0005 inches supports close-tolerance hole applications
• Bright/uncoated finish — no coating buildup to affect hole size or tool diameter
• Right-hand, two-flute straight configuration suited for short-chipping hard alloys

Compatibility

Designed as an OEM-style replacement or direct-use straight-flute carbide drill bit for applications requiring a wire size 13 (0.1850 inch) hole in chrome alloy, heat-treated alloy, nickel alloy, stainless steel, steel, and titanium alloy workpieces.

Installation Notes

Installation of carbide drill bits should be performed by a qualified machinist. Always power down and lock out the spindle before loading or changing tooling. Carbide tooling is brittle — avoid side loads, interrupted cuts without proper parameters, and contact with hard jaw surfaces during clamping. Verify spindle runout and confirm feeds and speeds are appropriate for carbide before engaging the cut.
