What It Is

This HSS black oxide jobber drill bit is designed for general-purpose drilling across a wide range of materials. It is well suited for use in maintenance, fabrication, production, and portable drilling applications.

Material & Construction

Manufactured from high-speed steel (HSS), this drill bit provides a balance of toughness and wear resistance for everyday drilling tasks. The black oxide surface treatment enhances abrasion resistance and helps reduce friction during operation.

135° Split Point Performance

The precision 135° split point geometry starts drilling immediately on contact and reduces walking. Sizes smaller than 1/16 have the 118 degree standard point. The flatter 135° angle is especially effective in harder metals where a standard 118° point may wander..

Jobber Length Design

Jobber length drill bits are the most common standard length used in drilling applications. This versatile length makes them suitable for a wide variety of tasks in both shop and field environments.

Applications

Commonly used for:

• General metal drilling
• Maintenance and repair work
• Fabrication and production drilling
• Portable drilling applications
• Drilling plastic and wood

Frequently Asked Questions

What is a black oxide drill bit user for?

Black oxide drill bits are used for general-purpose drilling in metal, plastic, and wood. The black oxide finish helps improve wear resistance and reduce friction.

What does “split point” mean?

A split point drill bit features a 135° tip geometry that starts drilling on contact and reduces walking compared to standard 118° drill bits.

What materials can this drill bit drill?

This drill bit is suitable for aluminum, brass, copper, steel, plastic, and wood.

What is jobber length?

Jobber length refers to the industry-standard drill bit length. It offers a balanced combination of flute length and rigidity, making it suitable for most drilling applications.

Is this drill bit suitable for stainless steel?

While it can drill some stainless applications, cobalt drill bits are generally preferred for harder stainless steels.
