Hertel C.402.0180 Jobber Drill 1.80mm Hss Oxide

Product Description

The HERTEL C.402.0180 is a high speed steel jobber-length drill bit ground to a 118-degree standard point angle and finished with an oxide coating. Sized at 1.80 mm (0.0709 inches) in diameter, it carries a 25 mm flute length and a 51 mm overall length. The straight-cylindrical shank seats cleanly in standard drill chucks and collet holders. Right-hand spiral flutes clear chips efficiently during through-hole and blind-hole drilling operations. This is a general-purpose drill intended for use by machinists, maintenance technicians, and toolroom professionals working in light-metal, plastic, and general shop materials.

The C.402.0180 fits into general-purpose drilling applications where small-diameter precision holes are required. Typical scenarios include pilot-hole drilling, fixture building, sheet-metal work, and light production drilling on manual drill presses, CNC machining centers, and handheld power tools. The 1.80 mm diameter falls within the 0.00 mm to 2.00 mm size range, making it appropriate wherever a sub-2 mm hole is specified. Sold individually, with a minimum order quantity of 12 units per order.

Key Features

• 1.80 mm (0.0709 inches) diameter for small-diameter precision hole work
• 118-degree standard point angle for general-purpose materials
• High speed steel construction provides hardness and heat resistance for typical shop use
• Oxide surface finish reduces friction and provides light corrosion resistance
• Right-hand spiral flutes promote efficient chip evacuation
• Straight-cylindrical shank compatible with standard chucks and collet systems

Compatibility

Designed as a general-purpose jobber drill for use in standard drill chucks and collet holders that accept straight-cylindrical shanks in the sub-2 mm diameter range.

Installation Notes

Install this drill bit in a properly sized collet or chuck and verify runout before beginning a drilling operation. Secure the workpiece firmly to prevent movement during cutting. Use appropriate cutting fluid or lubrication when drilling metals to extend tool life and improve hole quality. Inspect the cutting edges for wear or chipping and replace the bit if the point shows signs of dulling to avoid oversized or ragged holes.
