Hertel 83246603 Carbide Die Drill Bit 0.2010 in No. 7

Product Description

The HERTEL 83246603 is a solid carbide straight-flute die drill bit designed for precision drilling in hard and difficult-to-machine materials. Built from C2-grade carbide with a bright finish, it measures 0.2010 inches in diameter and corresponds to a No. 7 wire gauge size. The 140-degree notched point and web-thinned construction reduce thrust force and improve centering accuracy when entering hard workpieces. Right-hand cutting direction and a two-flute configuration make this bit suited for die work and tight-tolerance hole production. It weighs approximately 0.1 pounds and carries a diameter tolerance of +0.0000 to -0.0005 inches for consistent, repeatable results.

This drill bit is engineered for use in ferrous and high-strength alloy materials including steel, stainless steel, heat-treated alloy steel, chrome alloy, nickel alloy, and titanium alloy. It is equally effective as a primary or secondary workpiece material tool in those same material categories. Typical applications include die and mold shops, precision machining operations, and production environments where hole quality and tool life in hard materials are critical. It is suited for manual drilling machines, CNC machining centers, and drill presses where consistent feed rates can be maintained.

Key Features

• C2-grade solid carbide construction for hardness and wear resistance in ferrous alloys
• 140-degree notched point reduces thrust and improves entry accuracy
• Web-thinned design lowers cutting resistance and heat buildup
• Diameter tolerance of +0.0000 to -0.0005 inches ensures tight-fit hole quality
• Bright finish with right-hand cut and two-flute geometry for chip clearance
• No coolant-through requirement simplifies setup in standard drill configurations

Compatibility

Designed as an OEM-style replacement or direct-fit die drill bit for applications requiring a No. 7 wire size (0.2010 inches) straight-flute carbide drill in steel, stainless steel, heat-treated alloy, chrome alloy, nickel alloy, and titanium alloy workpieces.

Installation Notes

Installation and use of this drill bit should be performed by a qualified machinist or tooling professional. Secure the shank firmly in a compatible chuck or collet and verify runout before drilling. Power down and de-energize all equipment before changing tooling. Follow shop safety protocols and applicable OSHA machine guarding requirements when operating drilling equipment.
