What It Is

This solid carbide jobber length drill bit is a precision-ground twist drill designed for high-performance drilling in demanding applications. Unlike high-speed steel or cobalt drill bits, solid carbide provides significantly greater rigidity and wear resistance, making it well suited for abrasive materials and high-speed machining environments.

Solid Carbide Construction

Manufactured from solid carbide, this drill bit offers superior stiffness compared to HSS and cobalt tools. The increased rigidity minimizes deflection during drilling, helping maintain dimensional accuracy and hole quality. Solid carbide also performs reliably under elevated drilling temperatures, making it suitable for higher feed rates and production use.

Designed for Rigid Setups

Due to its rigidity and hardness, solid carbide performs best in stable, rigid setups such as CNC machines, machining centers, and drill presses. Proper tool holding and minimized runout are recommended to maximize tool life and performance.

Jobber Length Design

The jobber length configuration provides standard flute and overall length proportions suitable for a wide range of general drilling depths.

Applications

Solid carbide drill bits are especially effective in:

• Cast iron Aluminum
• Non-ferrous alloys
• Plastics
• Abrasive and composite materials

They are ideal for applications where wear resistance and dimensional stability are critical.

Frequently Asked Questions

What is the advantage of solid carbide over HSS or cobalt?

Solid carbide provides greater rigidity and wear resistance than HSS or cobalt. It allows higher feed rates, better dimensional accuracy, and improved performance in abrasive materials.

What machines should be used with solid carbide drill bits?

Solid carbide drill bits perform best in rigid setups such as CNC machines, machining centers, and drill presses where tool runout and vibration are minimized.

Can solid carbide drill bits be used in handheld drills?

While possible, they are best suited for rigid machines. Excessive vibration or runout in handheld drills can reduce tool life. Increased rigidity reduces tool deflection, improving hole accuracy and surface finish while extending tool life.

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.

What materials are solid carbide drill bits recommended for?

They are recommended for cast iron, aluminum, non-ferrous alloys, plastics, and other abrasive materials.

Are solid carbide drill bits suitable for high-speed machining?

Yes. Solid carbide performs well at higher speeds and feed rates when used in proper machine setups.
