Saber X-SET HSS-Co5 Cobalt Metric Twist Drill Set with BONUS Countersink – 8012-XM3

The Saber X-SET HSS-Co5 Cobalt Metric Twist Drill Set is an exceptional tool for both professional and DIY enthusiasts. This set features 25 pieces of high-speed steel cobalt drill bits, each carefully crafted to enhance your drilling experience. The sizes range from 1.0mm to 13.0mm with 0.5mm increments, providing versatility for various projects.

• • Saber 25 Piece HSS-Co5 (Cobalt) Twist Drill Set 1.0-13.0mm x 0.5mm rises

Understanding the composition of cobalt drill bits is essential for selecting the right tool. Cobalt, an element known for its hardness and wear resistance, significantly improves the performance of these drill bits. This is particularly beneficial when working with tough materials like stainless steel, where ordinary drill bits may struggle.

• • DIN338
  • 135° Split Point (crankshaft point).

The design of the drill bit, especially the 135° split point, allows for a smooth entry into the material. This design reduces the chances of the bit walking or slipping, which can lead to inaccuracies in drilling. By using a split point, the drill bit can penetrate harder materials more efficiently.

• • Split point is self centering and the short distance from the drill axis to the outer corners results in faster penetration, reducing the need for end thrust.
  • The 135° point should be used to cut harder steel materials especially in deep hole applications.

When tackling deep hole applications, the right drill bit can make all the difference. The 135° point is specifically engineered to handle such tasks, producing thicker chips that minimize work hardening. This feature is crucial for maintaining the integrity of the material being drilled, as excessive heat can lead to failure.

• • In these situations it will produce thicker chips minimising work hardening of the cavity.
  • Faster penetration reduces abrasion and friction along the cutting edges.
  • Cobalt HSS Twist drills are extremely hard and provide superior performance and increased tool life especially in stainless steel and high tensile steel.

The durability of cobalt HSS twist drills is unmatched, providing a longer tool life compared to standard HSS bits. This makes them a cost-effective choice for contractors who rely on consistent performance across multiple jobs. Investing in high-quality drill bits can lead to significant savings in replacement costs over time.

• • Bronze Finish (gold oxide) surface treatment. The metallic brown coloured low temperature temper treatment is normally only used on cobalt tools for identification purposes.

The bronze finish, or gold oxide surface treatment, not only provides a distinct look but also enhances the tool’s resistance to rust and corrosion. This feature is especially important in environments where moisture is a concern, ensuring that your tools remain in optimal condition for longer periods.
