Hertel C.402.1650 Jobber Drill 16.50mm Hss 118-deg

Product Description

The HERTEL C.402.1650 is a high speed steel jobber-length drill bit ground to a 118-degree standard point angle and finished with an oxide coating for added lubricity and corrosion resistance. Sized at 16.50 mm (0.6496 inches) in diameter, it runs a spiral two-flute geometry in a right-hand cutting direction, producing clean, consistent chip evacuation in a wide range of metals and plastics. With an overall length of 181 mm and a flute length of 132 mm, this is a general-purpose bit sized for production and maintenance drilling where a straight-cylindrical shank and standard geometry are required.

This jobber drill is suited for general-purpose metalworking in fabrication shops, maintenance facilities, and light manufacturing environments. It fits standard drill chucks and is appropriate for use in drill presses, CNC machining centers, and hand-held power drills wherever a 16.50 mm bore is needed. No coolant-through capability is featured, making it best applied in air-cooled or flood-cooled external setups at appropriate surface speeds for HSS tooling.

Key Features

• 16.50 mm (0.6496 inch) diameter for precise bore sizing
• 118-degree standard point angle for general-purpose entry into most workpiece materials
• High speed steel construction offers toughness across a broad range of materials
• Oxide finish reduces friction and provides light corrosion resistance
• Two-flute spiral geometry promotes efficient chip removal
• Straight-cylindrical shank fits standard three-jaw and collet-style drill chucks

Compatibility

Designed as a general-purpose jobber drill for use in standard drill chucks accepting straight-cylindrical shanks, suitable for drill presses, machining centers, and portable power drills requiring a 16.50 mm bit diameter.

Installation Notes

Installation and use should be performed by a qualified machinist or maintenance technician familiar with metal-cutting tooling. Secure the straight-cylindrical shank fully in a properly sized chuck before operation and confirm the spindle is at a suitable RPM for the material and bit diameter. Power down and de-energize the machine before changing bits or adjusting chuck position. Do not exceed the recommended feed rate for HSS tooling, as overheating without coolant will degrade the cutting edge.
