Description
Carbide-Tipped Metal Drill Bit
A metal drill bit with a carbide insert, designed for demanding applications where standard HSS drills are no longer sufficient. Thanks to the use of extremely hard materials, it offers significantly improved durability and cutting performance.

Product Features
Extreme hardness and durability of the cutting edge
YG8 cemented carbide reaches a hardness of approx. 90 HRA (~70 HRC), which means:
-
the cutting edge wears much more slowly
-
it retains sharpness even during intensive use
-
it allows drilling in harder-to-machine materials
This solution is especially appreciated by users working in continuous or serial production.
High wear resistance
Compared to standard drill bits:
-
the cutting surface wears down much more slowly
-
the tool maintains its performance parameters for longer
-
the need for frequent drill replacement is reduced
Result: savings in time and operating costs
Stable performance at high temperatures
Drilling in metals generates very high temperatures. Cemented carbide:
-
does not lose hardness as quickly as HSS
-
does not dull due to overheating
-
ensures stable cutting even under higher loads
Important operating information (honest and professional)
Cemented carbide, in addition to its advantages, also has specific properties:
-
it is hard but brittle
-
it does not tolerate impacts or hammering action
-
it is sensitive to lateral loads and misalignment
Therefore, for best results it is recommended to:
-
use stable guidance (e.g. a drill press)
-
avoid “manual angled pressure”
-
work with properly selected speed and feed rate
