Center Spotting Drill
Product Overview: HSS Center Drill Standard Type 90° – CD90 Series
【Product Features & Why We Recommend It】
- Japanese Brand Professional Quality: Originating from a professional Japanese cutting tool brand with stable quality — recommended for users with dual demands on center positioning and chamfering/deburring who want to minimize tool change time.
- 90° Large Point Angle Dual-Purpose Design: Features a 90° drill point angle design — providing a shallower positioning cone compared to the standard 60° version (CD60), while simultaneously offering chamfering and deburring functionality, recommended for applications requiring both center positioning and hole-mouth chamfering within the same operation, effectively reducing tool change time and improving machining efficiency.
- Chamfering and Deburring Dual-Use Advantage: The 90° point angle geometry is not only suitable for pre-drilling center spotting, but can also be directly used for 90° hole-mouth chamfering and workpiece deburring operations — recommended as the economical and practical choice for completing both spotting and chamfering in a single tool.
- HSS Standard High-Speed Steel Substrate: Manufactured with high-speed steel (HSS), achieving a favorable balance between cost and performance — recommended for daily center positioning and chamfering operations on general-hardness materials, economical and practical.
- 26 Specification Wide Coverage: Available in diameter 0.3–10mm and overall length 31–100mm across 26 specifications — recommended for flexible selection based on workpiece hole diameter and chamfer dimensions, covering all types of center positioning and chamfering requirements.
【Machining Applications & Uses】
- Primary Use: 90° center spot drilling, hole-mouth 90° chamfering, and workpiece deburring operations.
- Recommended Work Materials:
- P-Class (Carbon Steel / Alloy Steel): Structural steel, carbon steel, and alloy steel — the HSS substrate delivers stable center positioning and chamfering cutting performance, representing the ideal application scenario for this series.
- K-Class (Cast Iron): Cast iron and gray iron — the HSS substrate provides basic wear-resistant positioning drilling tool life.
- N-Class (Non-Ferrous Metals): Aluminum alloys, pure copper, brass, and other non-ferrous metals — recommended for use with appropriate cutting fluid to ensure stability and surface quality during center positioning and chamfering.
