Burr Free Aluminium Drilling 2 Flutes Carbide Step Drill with Internal Coolant

This 2-blade internally hard alloy step drill is designed for burr free drilling and efficient multi-stage hole processing of aluminum materials. using advanced precision grinding technology by maded AMG, it has excellent cutting performance and an internal cooling channel that effectively enhances heat dissipation and improves chip removal. It is particularly suitable for high-speed CNC drilling operations on aluminum and other non-ferrous metals.

The cutting tool is made of ultra-fine particle hard alloy rod, which has high toughness and wear resistance, ensuring long service life and consistent aperture. The straight groove structure, with a stepped blade shape, can complete many aperture machining in one time. The drilling edge is smooth and free of burrs, greatly improving machining efficiency and reducing subsequent secondary processes such as deburring

Applications:

• Burr-free step hole drilling in aluminium and non-ferrous metals

• Deep hole and blind hole machining in aerospace and automotive aluminium parts

• Precision drilling for mold bases and aluminium fixtures

• Multi-step hole machining in CNC aluminium component manufacturing

• High-speed aluminium drilling requiring efficient heat and chip management

Working Principle:
The drill’s internal coolant channels deliver coolant directly to the cutting edge, efficiently reducing heat and lubricating the cutting surface. This enhances chip evacuation and minimizes thermal deformation and tool wear. The straight flute design promotes smooth cutting and reduces burr formation, while the step geometry allows machining of multiple hole diameters in one pass with high accuracy. Together, these features enable precise, burr-free holes and increase machining productivity.

Advantages:
✅ AMG precision grinding ensures sharp cutting edges and tight dimensional tolerances
✅ Internal coolant system improves heat dissipate and chip removal, extending tool life
✅ Step drill design enables efficient multi-diameter drilling in one operation
✅ Straight flute reduces burrs and ensures smooth hole
✅ Ultra-fine carbide material offers high toughness and wear resistance
✅ OEM services available including free logo engraving and customer packaging
✅ Stringent 4-step quality inspection guarantees consistent tool performance
