Product Selection Differences for Stub Drill Bits

When selecting Stub Drill Bits, consider the following key differences:

1. Material: Stub drill bits can be made from various materials such as high-speed steel (HSS), cobalt, carbide, or coated materials like TiN (Titanium Nitride). Each material offers different levels of hardness and durability, impacting the bit's performance and longevity.

2. Coating: Some stub drill bits come with coatings like TiN, TiCN (Titanium Carbo-Nitride), or TiAlN (Titanium Aluminum Nitride) to enhance wear resistance and reduce friction. Coated bits typically last longer and perform better in certain materials.

3. Flute Design: Flute design affects chip removal and heat dissipation. Parabolic or twisted flute designs can improve chip evacuation, reducing clogging and overheating during drilling.

4. Point Angle: The point angle of the bit determines the type of material it is best suited for. Common point angles for stub drill bits are 118 degrees and 135 degrees. A 118-degree point is suitable for softer materials, while a 135-degree point is better for harder materials.

5. Shank Type: Consider the shank type of the drill bit (such as round, hex, or SDS) to ensure compatibility with your drilling equipment. The shank type influences the bit's stability and grip in the chuck.

6. Size Range: Stub drill bits come in various sizes, so ensure you select the right diameter for the specific drilling task at hand.

7. Manufacturer Reputation: Consider reputable brands known for their quality and consistency in manufacturing drill bits. Reliable manufacturers often provide better performance and durability.

By evaluating these key differences, you can choose stub drill bits that best suit your drilling needs in terms of material compatibility, longevity, performance, and efficiency.
