Hertel C.402.1260 Jobber Drill Bit 12.60 Mm Hss

Product Description

The HERTEL C.402.1260 is a high speed steel jobber-length drill bit designed for general-purpose drilling in metal, wood, and plastics. It features a 118-degree standard point angle for reliable center-starting and clean entry on flat and curved surfaces. The oxide coating reduces friction and provides light surface protection during cutting. At 152 mm (5.98 inches) overall length with a 114 mm (4.49 inches) flute length, this is a standard jobber proportion suited to bench drills, drill presses, and hand-held power drills. It weighs 0.15 pounds. Machinists, maintenance technicians, and fabricators reach for this size when drilling holes near 12.60 mm (0.4961 inches) in diameter.

This bit is sized for general-purpose material removal in production and maintenance environments. The 12.60 mm diameter falls in the 12.50 to 15.00 mm size range, making it a common selection for metric fastener clearance holes and similar applications. The straight-cylindrical shank fits standard drill chucks without an adapter. Right-hand spiral flutes evacuate chips efficiently during through-hole and blind-hole drilling operations in light to medium-duty setups.

Key Features

• 12.60 mm (0.4961 inch) diameter for metric and fractional hole work
• 118-degree standard point angle for general-purpose entry and center-starting
• High speed steel construction handles a broad range of workpiece materials
• Oxide coating reduces friction and extends tool life in typical shop conditions
• Two spiral flutes promote chip evacuation in both through and blind holes
• Straight-cylindrical shank seats in standard keyless or keyed drill chucks

Compatibility

Designed as a general-purpose jobber drill bit compatible with any drill press, CNC drill head, or hand-held power drill fitted with a chuck sized to accept a straight-cylindrical shank in the 12.60 mm diameter range.

Installation Notes

A licensed machinist or qualified technician should secure the shank fully in the chuck before operation and verify chuck key removal before starting the spindle. Always clamp the workpiece securely to prevent rotation during drilling. Appropriate cutting fluid or coolant is recommended when drilling hardened or stainless materials to preserve edge life. Follow applicable shop safety standards and machine manufacturer guidelines for speed and feed selection.
