Metal Drill Bits in Ghana – HSS, Cobalt, Titanium-Coated & Carbide Drill Bits | CETECH Ghana

Metal drill bits are precision-engineered cutting tools designed to drill through tough materials such as stainless steel, cast iron, aluminum, and structural steel. Made from High-Speed Steel (HSS), Cobalt (M35/M42), Titanium-coated steel, or Carbide, these bits feature hardened, sharp-angled tips—commonly 118° or 135° split-point geometry—for accurate penetration and reduced walking on metal surfaces.

At CETECH Ghana, we supply high-quality metal drill bits for automotive repair, metal fabrication, construction, industrial workshops, and professional CNC applications. Available online and in physical stores across Ghana, with bulk supply and contractor support.

If you are searching for metal drill bits in Ghana, HSS drill bits, cobalt drill bits for stainless steel, titanium drill bits, carbide drill bits, or drill bit sizes from micro to larger diameters, this guide provides everything you need to choose correctly.

What Are Metal Drill Bits?

Metal drill bits are cutting tools specifically designed to create holes in metal surfaces. Unlike wood drill bits or masonry bits, they are engineered to withstand:

• High friction
• Elevated temperatures
• Hard material resistance
• Continuous mechanical stress

They are commonly used in:

• Automotive repair
• Steel fabrication
• Mechanical workshops
• Construction sites
• Industrial maintenance

The right drill bit ensures clean holes, reduced tool wear, and improved safety.

Materials Used in Metal Drill Bits

The performance of a metal drill bit depends largely on its material composition.

1. HSS (High-Speed Steel) Drill Bits

HSS drill bits are the most common and versatile option for general metalworking.

Key Characteristics:

• Durable and budget-friendly
• Suitable for mild steel, aluminum, and brass
• Heat-resistant under moderate drilling speeds
• Ideal for general-purpose fabrication

HSS bits are widely used in Ghana for construction and workshop applications due to their affordability and reliability.

2. Cobalt Drill Bits (M35/M42)

Cobalt drill bits contain 5% to 8% cobalt content, enhancing hardness and heat resistance.

Key Benefits:

• Highly heat-resistant
• Essential for drilling stainless steel
• Suitable for hard alloys
• Maintains cutting edge at high temperatures

Cobalt (M35/M42) is commonly used for automotive and heavy fabrication work in Ghana.

Note: Cobalt bits are harder but more brittle, meaning they can chip if misused.

3. Titanium-Coated Drill Bits (TiN Coating)

Titanium Nitride (TiN) coating reduces friction and heat buildup.

Advantages:

• Faster drilling
• Extended lifespan
• Reduced wear
• Improved heat resistance

Titanium-coated bits are commonly used on:

• Steel
• Aluminum
• Brass

They are popular for contractors seeking balance between cost and durability.

4. Carbide Drill Bits

Carbide drill bits offer extreme hardness and are used in professional environments.

Features:

• High-speed cutting capability
• Excellent wear resistance
• Suitable for CNC machines and drill presses
• Long service life

However, carbide bits are brittle and can break easily if misaligned or used in handheld drills improperly.

These are best for industrial workshops and manufacturing facilities.

Geometry and Tip Design

The design of the drill bit tip directly affects performance.

118° Point Angle

• Standard design
• Suitable for softer metals
• Ideal for general-purpose drilling

135° Split-Point

• Reduces walking (sliding on metal surface)
• Improves centering accuracy
• Ideal for hard metals such as stainless steel

Split-point geometry eliminates the need for a center punch in many cases.

Coatings That Improve Performance

Metal drill bits often feature protective coatings:

Titanium Nitride (TiN)

• Gold-colored coating
• Reduces friction
• Improves heat resistance
• Extends tool life

Black Oxide

• Enhances corrosion resistance
• Reduces friction
• Cost-effective improvement

Coatings significantly impact durability, especially under heavy use.

Shank Styles

The shank connects the drill bit to the chuck.

Straight Shank

• Standard and widely compatible
• Used in most drills

3-Flat Shank

• Prevents slippage
• Improves grip in chuck
• Ideal for high-torque drilling

Choosing the right shank style prevents drill bit spinning inside the chuck.

Standard Sizes (Metric):

Standard Sizes (Imperial / Fractional):

• 1/16″
• 3/32″
• 1/8″
• 5/32″
• 3/16″
• 7/32″
• 1/4″
• 5/16″
• 3/8″
• 7/16″
• 1/2″

This size range ensures compatibility with most metal drilling applications—from light fabrication to heavy-duty industrial work.

Contractors and workshops in Ghana often purchase full sets to cover multiple diameters without interruption.

Types of Metal Drill Bits

Twist Drill Bits

The most common type, used for general metal drilling.

Step Drill Bits

Designed for:

• Sheet metal
• Enlarging existing holes
• Fast drilling of multiple diameters

One bit can accomplish multiple hole sizes.

Annular Cutters

Used for:

• Industrial steel drilling
• Magnetic drill machines
• Structural steel fabrication

They remove a ring of metal rather than the full core, improving cutting efficiency.

Applications in Ghana

Metal drill bits are essential in:

Automotive Repair

• Engine blocks
• Brackets
• Automotive chassis

Cobalt bits (M35/M42) are preferred for hardened automotive steel.

Construction

• Steel framing
• Metal support structures
• Roofing metal sheets

Fabrication Workshops

• Gates and metal furniture
• Industrial brackets
• Custom metal pieces

Industrial Manufacturing

• CNC machining
• Drill press operations
• Repetitive production drilling

Maintenance and Best Practices

Proper maintenance extends drill bit life and improves hole quality.

Best Practices:

1. Use cutting lubricant (oil or wax).
2. Maintain correct drilling speed.
3. Avoid excessive pressure.
4. Keep bits sharp.
5. Store in protective cases.

Using lubricant reduces heat buildup and prevents premature wear.

Common Mistakes to Avoid

• Using HSS bits on hardened stainless steel
• Drilling at high speed without lubricant
• Applying too much pressure
• Using brittle carbide bits improperly in handheld drills

Selecting the correct material and drill speeds helps prevent breakage and tool damage.

Comparing HSS, Cobalt, Titanium, and Carbide

Type	Best For	Durability	Cost Level
HSS	General steel, aluminum	Moderate	Budget
Cobalt (M35/M42)	Stainless steel	High	Mid-High
Titanium-Coated	Faster drilling, longer life	High	Mid
Carbide	CNC & industrial press	Very High	Premium

For most Ghana workshop users, cobalt bits deliver superior performance for stainless steel and hard alloys.
