External cooling of carbide drills

Item No.：

Summary

External cooling of carbide drills helps to dissipate heat generated at the cutting edges of the drill. By directing a stream of coolant onto the drill bit and workpiece, it assists in removing heat from the cutting zone, preventing excessive heat buildup and reducing thermal stress on the tool.

Product Details

The main purpose of external cooling of carbide drills is to effectively manage heat dissipation and improve cutting performance in carbide drilling:
Heat Dissipation: External cooling of carbide drills helps to dissipate heat generated at the cutting edges of the drill. By directing a stream of coolant onto the drill bit and workpiece, it assists in removing heat from the cutting zone, preventing excessive heat buildup and reducing thermal stress on the tool.
Chip Evacuation: External coolant aids in chip evacuation by washing away chips from the cutting zone. This helps prevent chip clogging and promotes uninterrupted drilling, ensuring smooth and efficient chip flow.
Lubrication: Coolant used in External cooling of carbide drills acts as a lubricant, reducing friction between the drill and the workpiece. This lubrication minimizes heat generation and friction-related wear, contributing to improved tool performance and extended tool life.
Improved Surface Quality: External cooling of carbide drills can enhance the surface quality of the drilled hole by reducing the likelihood of burr formation, improving hole accuracy, and promoting better chip control. It results in smoother and cleaner holes, reducing the need for secondary operations or post-processing.
Increased Productivity: By managing heat and improving chip evacuation, External cooling of carbide drills enables higher cutting speeds and feeds, leading to increased productivity in drilling operations. It allows for faster and more efficient material removal, reducing machining cycle times.

Application feature:

Used for: gray cast iron, ductile iron, stainless steel, alloy steel, and other common materials processing, centering ability, stable size accuracy and good surface quality, suitable for processing systems with excellent rigidity occasions, better internal cooling effect.
