Our drill bits for aluminum are designed with 0.4μm carbide substrates, enabling their higher tool rigidity and extended tool life.

Oerlikon Coating Technology

Our aluminum drill bits can be customized with Oerlikon advanced coatings, which feature uniform coating thickness and high adhesion.

High-Helix Polished Flutes

High-helix flutes feature polished flute surfaces with optimized chip channels, greatly decreasing the flute surface roughness.

140° Point Angle Design

Precisely-ground 140° point angles can ensure the drip tip consistency with the symmetrical chisel edge and accurate point design.

Sharp Cutting Edge Preparation

Micro-honed cutting edges feature the controlled edge radius and optimized edge profiles, ensuring excellent tool sharpness and consistency.

Reinforced Web Core

The reinforced web core featuring the gradual core taper can maintain the tool rigidity based on the cross-sectional geometry.

Aluminum Drill Bit Geometry Breakdown

1.Solid Carbide Construction for Dimensional Stability

0.4μm ultra-fine carbide substrates featuring 12% cobalt content, 92.5 HRA hardness, 14.10 g/cm³ density, and 4200 MPa transverse rupture strength can deliver higher tool rigidity, ensuring accurate tool diameters and superior dimensional accuracy.

2.Oerlikon Coating Technology for Lower Friction

Our drill bits for aluminum are typically uncoated. However, Oerlikon DLC advanced coatings can be combined to promote smooth cutting with superior adhesion.

3.High-Helix Polished Flutes for Efficient Chip Flow

Mirror-polished flutes with helix angles from 35° to 40° and smooth channel profiles are specialized for optimizing the chip flow.

4.130° Point Angle Design for Accurate Positioning

The precisely-ground 130° split point can achieve the optimized cutting engagement with a thinned chisel edge and symmetrical cutting lips.

5.Sharp Cutting Edge Preparation for Edge Consistency

Micro-honed cutting edges are specialized with the controlled micro-edge hone from 5 to 15 μm, delivering higher edge sharpness and edge consistency.

6.Reinforced Web Core for Higher Rigidity

The tapered web core can keep the balance between the tool rigidity and flute volume, preserving the structural stiffness.

What type of drill bits are needed for aluminum?

It mainly depends on your machining requirements. If you need to use the low-speed machine for daily work, the high-speed steel drill bits would be sufficient, and the HSS-TiN coating would enhance wear resistance and tool life. If you are using CNC machines for production, our D2500-series drill bits for aluminum are an ideal choice for machining aluminum alloys and other non-ferrous metals.

What are the common problems when machining aluminum?

Chip evacuation
Tool wear & short lifespan
Poor surface finish quality
Heat management
Material adhesion
Challenges in high-speed machining
High unit costs for hole-machining

Our D2300-series drill bits for aluminum with the upgraded geometry design have significantly improved these issues, with double margins in edge design, which will dramatically enhance chip removal and heat resistance.

What industries are suitable for using drill bits for aluminum?

Our D2500-series drill bits for aluminum can be applied in various industries to promote chip removal, hole deburring, and tool lifespan. Aerospace is a common industry that uses drill bits for aluminum, which are used for precise hole-making. 3C and the automotive industry are also suitable for using aluminum drill bits because they need to efficiently machine micropores for mass production. Drill bits for aluminum are also ideal for machining high-silicon aluminum and thin-wall parts, enabling us to offer drilling stability under special operating conditions.

Should you drill aluminum fast or slow?

You should generally drill the aluminum at higher cutting speeds and feed rates. For solid carbide drill bits, the recommended cutting speeds are commonly from 150 to 500 m/min, while the feed rates typically range from 0.08 to 0.35 mm/rev based on the tool diameters. Higher speeds and feeds are required to decrease the built-up edge with improved surface finishes. Combined with solid carbide drill bits with a higher helix, minimal chip adhesion and improved chip evacuation can be attained.

How do you drill a hole in aluminum?

To efficiently drill holes in aluminum, you need to choose specialized drill bits with sharp cutting edges, such as solid carbide drill bits for aluminum with polished flutes. You should first secure the workpiece material, and then use high cutting speeds and stable feed rates. You can use cutting fluids to decrease tool friction and prevent chip adhesion. Aluminum drill bits with high helix geometry can ensure smooth drilling and surface finishes.

How to drill a screw into aluminum?

If you need to drill a screw into aluminum, you should use aluminum drills to drill the pilot hole. You need to choose suitable drill bit sizes according to the screw diameter to ensure the correct thread engagement. Remember to use high cutting speeds and light feed pressure to prevent material deformation. In threading, self-tapping screws for aluminum can be used to ensure higher dimensional accuracy.
