Description

This 4-piece countersink deburring tool set is specifically designed for precision machining on various materials. This set can accommodate diverse hole diameters, enabling easy, accurate chamfering and efficient deburring. Combining premium materials with meticulous craftsmanship, it withstands continuous machining demands. Its compact design ensures quick mastery even for novices, without complex adjustments. This significantly reduces processing time while maintaining machining precision.

Key Features

High-strength and Enduring: Crafted from high-strength 4241 high-speed steel with a titanium coating, this tool delivers enhanced hardness, improved corrosion tolerance, consistent machining performance, and extended service life.    

Meet Multi-Size Processing Needs: This 4-piece set offers precision-matched tools for common hole diameters—2-5 mm, 5-10 mm, 10-15 mm, and 15-20 mm—with corresponding 6mm, 8mm, 10mm, and 12mm shank sizes—designed to support a broad spectrum of everyday machining needs.

Unique Chip Removal Structure: The groove-style chip removal design supports efficient, continuous chip evacuation—enhancing process stability and contributing to a safer machining experience.

Reliable Machining Performance: Its 90° chamfered tip, crafted with precision, enables accurate countersinking in circular or tapered holes and works well for edge chamfering. The result is consistently smooth cuts and cleanly finished surfaces.

User-Friendly: Compatible with bench drills, its distinctive slotted tapered surface prevents machining vibrations and wobbles that could impact chamfering quality. You only need to run the drill at minimum speed and use gentle pressure for reliable machining.

Details

Well-made Cutting Edges: The cutting edge is hardened and honed to provide excellent sharpness, smooth cutting without jamming, and improve efficiency.                                       

Sleek and Round Edges: They further enhance the product's texture and usage safety.

Application

This set is widely applicable to various materials, including timber, fibreboard, chipboard, plywood, plastics, aluminium sheets (hardness < 28 degrees), metals with hardness < 25 degrees, and thin iron sheets. It is suitable for diverse scenarios such as domestic DIY projects, repair shops, general construction/engineering work, and small-scale workshops.

Notes

• Please check the size carefully before ordering.
• Please note that hand drills are not recommended, as they may lead to deviations in machining accuracy.
• Please allow the slight color difference caused by the shooting light and the 1-3 cm error due to manual measurement, and make sure you do not mind before ordering.
