Solid Carbide Drills with Straight Groove for ISO K N Cast Iron / Excellent Self Centering Capability
The First Choice for Precision Hole Drilling in Cast Iron.
Feature Advantage:
Non-coated.
Suitable for short chip materials such as cast iron and silicon aluminum alloy.
Excellent self-centering capability for efficient machining and machining of workpieces with hole machining accuracy of H7.
The machined holes achieve high position, straightness and surface quality.
Optimized drill tip structure for better cutting performance.
∅4 - ∅25 Diameter, complete types.
5D, 15D, all kinds of lengths are complete.
All types are available in both internal and external cooling to meet the requirements of various machine tools.
Technical Information:
Typical application of integral alloy drill bits:
Small diameter hole
Tight or precision tolerance hole
The hole shorter than a deep hole
Chip formation and chip evacuation are important issues in drilling. It depends on the workpiece material, blade geometry selection, coolant pressure, capacity, and cutting parameters.
Chip clogging can cause the drill bit to move radially and affect hole quality, bit life and reliability.
The drill bit is mounted on the shank chuck and its circumferential runout must be less than 0.02 mm.
Recommended Cutting Parameters:
When using this series of tools for the first time, the cutting is performed according to the recommended cutting speed of 90% or the feed rate of 85%. When the cutting condition is stable, the cutting speed and the feed are increased one by one.
Cutting parameters are recommended for water soluble cutting fluids.
Use a defect-free, clean chuck when installing the drill and control the drill runout to within 0.02 mm.
The recommended cutting parameters are for applications where the hole depth is below 5D.
The recommended cutting parameters are externally cooled drills, which can be increased by 10%-15% depending on the situation.
