What It Is

Manufactured from M1 high-speed steel for general-purpose metal drilling 135° split point tip self-centers and reduces walking compared to 118° tips Black and gold surface treatment enhances durability and wear resistance 3-flat shank provides extra secure holding power in the chuck Suitable for drilling steel, iron, aluminum, and other machinable metals Ideal for contractor, maintenance, and fabrication applications

Split Point Advantage

The 135° split point tip helps reduce walking and allows the drill to start more accurately without excessive thrust. Compared to conventional 118° drill points, the split point design improves centering and control during drilling.

Black & Gold Surface Treatment

The black and gold finish provides added surface protection and improved wear resistance during repeated use in metalworking environments.

3-Flat Shank Design

The 3-flat shank creates a secure grip inside the chuck, reducing slippage under load and improving torque transfer during drilling.

Reduced Shank Design (Silver & Deming Style)

This drill bit allows larger drill diameters to fit into standard 1/2" drill chucks, expanding the drilling capacity of portable drills and drill presses.

The black and gold finish enhances surface lubricity while helping protect against corrosion, making it a dependable choice for professional and industrial use.

Applications

Commonly used for:

• General steel and metal drilling
• Maintenance and repair work
• Contractor and jobsite applications
• Fabrication and shop use

Frequently Asked Questions

What is M1 high-speed steel?

M1 is a general-purpose high-speed steel commonly used in contractor-grade drill bits. It provides durability and wear resistance for everyday metal drilling.

What is a split point drill bit?

A split point drill bit features a 135° tip geometry designed to start drilling on contact. It reduces walking and improves centering accuracy compared to standard 118° point drill bits.

What materials can this drill bit drill?

This drill bit is suitable for steel, iron, aluminum, and other machinable metals.

What is a reduced shank drill bit?

A reduced shank drill bit has a smaller shank diameter than the cutting diameter, allowing large drill sizes to fit into smaller drill chucks. Silver & Deming drill bits typically have a 1/2" shank for use in standard drills.

Can this drill bit be used in a hand drill?

Yes. This drill bit is compatible with drill presses, handheld drills, and CNC machines using standard chucks.

What does a 3-flat shank do?

A 3-flat shank improves grip inside the chuck and reduces the chance of slipping during drilling.
