Key Considerations for Cobalt Spot Drill Bits

When selecting Cobalt spot drill bits, there are several key considerations to keep in mind:

1. Cobalt Percentage: Higher cobalt percentage results in increased strength and heat resistance of the drill bit. Look for drill bits with a cobalt percentage of at least 5%.

2. Material Compatibility: Ensure that the Cobalt spot drill bits are suitable for the material you'll be drilling into, such as stainless steel, hardened steel, or other tough metals.

3. Drill Bit Size: Choose the appropriate size of the spot drill bit for the application to ensure precision and accuracy in drilling.

4. Point Angle: The point angle of the drill bit affects the drilling performance. Common point angles for spot drill bits are 90 degrees and 120 degrees.

5. Coating: Look for Cobalt spot drill bits with a coating such as TiN (Titanium Nitride) or TiALN (Titanium Aluminum Nitride) for enhanced wear resistance and extended tool life.

6. Brand Reputation: Consider purchasing from reputable brands known for their quality and durability in drill bits.

7. Price and Value: Balance between the price of the drill bits and the value they provide in terms of performance, durability, and longevity.

By considering these factors, you can choose Cobalt spot drill bits that are best suited for
