Description
SOLID CARBIDE METRIC DRILLS
FROM 3-19.5MM (55-65HRC - Please see hardness for each size)
FOR EXTREME DRILLING CONDITIONS
These specially made solid carbide drills will cut through almost all materials with high tolerance, through hardened steels, and all stainless alloy & cast steels.
Broken taps and easy outs can be drilled out using these drills.
Carbide drills provide faster cutting rates, longer tool life, better positional and dimensional accuracy and improved surface finish. Shorter cycle times and tighter tolerances translate into maximum machine utilization, better part quality and optimum hole making cost savings.
Solid carbide drill bits with a hardness of 65HRC are considered to be extremely hard and wear-resistant. This high level of hardness allows these drill bits to maintain their sharpness and cutting ability for longer periods of time, even when drilling into tough materials.
65HRC Drills
Drilling with solid carbide drill bits with a hardness of 65HRC requires careful attention to cutting parameters, such as cutting speed, feed rate, and coolant use. These drill bits are designed to operate at high speeds and require sufficient coolant to prevent overheating and premature wear.
When drilling with solid carbide drill bits with a hardness of 65HRC, it's important to use the correct cutting speed and feed rate for the material being drilled. A slower cutting speed and lower feed rate may be required when drilling harder materials, while softer materials may allow for higher cutting speeds and feed rates.
It's also important to ensure that the drill bit is held securely in the drill chuck to prevent slipping or breakage during drilling. Using a proper drill press or machine tool with adequate clamping force is recommended.
Overall, solid carbide drill bits with a hardness of 65HRC are a durable and effective choice for drilling into tough materials, but careful attention to cutting parameters and tool handling is required to ensure their best performance and longevity.
