## Summary description

The KWB COBALT HSS CO twist drill bit is a high-performance tool designed for drilling in hard materials. Featuring a 1 mm diameter and right-hand rotation, this cobalt-alloyed drill bit provides increased heat resistance and durability. It is compatible with standard drill chucks and is ideal for precise metalworking applications, ensuring clean and efficient drilling results for professional and DIY projects.

## Long description

The KWB COBALT HSS CO twist drill bit is a high-performance precision tool engineered for demanding drilling tasks in hard materials. With a 1 mm diameter and a 5% cobalt alloy composition, this drill bit offers exceptional heat resistance and structural durability, making it a reliable choice for both professional metalworking and intricate DIY projects. Its design features a 135-degree tip angle with cross-ground geometry according to DIN 1412 C, which ensures excellent self-centering capabilities and prevents the bit from wandering on the workpiece surface.
Advantages
This drill bit stands out due to its industrial-grade construction and specialized cobalt alloy, which significantly extends the tool's lifespan when working with abrasive or heat-sensitive materials. The precision-ground cutting edges provide clean, accurate holes with minimal burr formation, while the self-centering tip reduces the need for pre-punching. Its robust design maintains performance even under high thermal stress, ensuring consistent results across a wide range of metallic and synthetic surfaces.
Suitable for
Drilling stainless steel grades A2 and A4
Working with alloyed and unalloyed steel
Processing cast iron and cast steel
Drilling into bronze and various plastics
Precision metalworking and thin sheet metal applications
This drill bit is not intended for use with masonry, concrete, or stone, as the high-speed steel composition is optimized for metal and plastic rather than abrasive mineral materials. Additionally, due to its small 1 mm diameter, it is not suitable for heavy-duty drilling tasks that require high torque or large hole diameters, as the bit may be prone to snapping if subjected to excessive lateral pressure.
Key specifications
Type: Twist drill bit
Diameter: 1 mm
Material: 5% Cobalt alloyed HSS
Tip angle: 135 degrees
Geometry: DIN 1412 C cross-ground
Rotation: Right-hand
Color: Bronze
To achieve the best results, ensure the drill bit is securely fastened in a compatible drill chuck. Begin drilling at a moderate speed, applying steady, controlled pressure to allow the self-centering tip to engage with the material. For harder metals like stainless steel, it is recommended to use a suitable cutting oil to reduce friction, dissipate heat, and prolong the sharpness of the cutting edges. Always maintain a perpendicular angle to the workpiece to prevent bit breakage.
What to consider before purchase
Verify that your drill chuck is capable of securing a 1 mm diameter shank.
Ensure the material you intend to drill is compatible with HSS-CO specifications.
Consider the fragility of small-diameter bits and use appropriate feed rates.
For optimal performance and longevity, always use a cooling lubricant when drilling stainless steel or hard alloys, and avoid applying excessive side force to prevent the drill bit from snapping.
