D7.41xL23.8xD10xL105 hard alloy internally cooled straight groove
drill bit is designed specifically for high-precision deep hole
machining of automotive parts. Made of ultra-fine particle solid
hard alloy (HM), it has excellent wear resistance, anti chipping
performance, and outstanding thermal stability.
Product features:
Excellent wear resistance: The hard alloy material ensures
excellent durability and stability of the drill under high load and high-speed machining conditions
Internal cooling design: The built-in cooling channel can
effectively deliver the coolant directly to the cutting area,
reduce temperature, minimize tool wear, and improve chip removal
efficiency to ensure smooth machining process.
Accurate guiding ability: The straight groove geometry structure
enhances the guiding accuracy of the drill bit, ensuring stability
during the drilling process
High thermal stability: The drill bit can effectively control
temperature changes in high-speed and high load processing
environments, avoiding tool damage caused by overheating.
Suitable for automotive manufacturing: Designed specifically for
high load deep hole machining in automotive parts manufacturing, it
can improve hole consistency and optimize overall machining
efficiency.
Application areas:
This drill bit is widely used in automotive manufacturing,
especially in machining engine parts, transmission systems, and
other precision mechanical parts, providing efficient and stable
deep hole machining solutions
