---

• The strength, durability, and efficacy of a drill bit are determined by its composition. High-speed steel (HSS) or cobalt drill blades are recommended for drilling aluminum. HSS drill blades are inexpensive, sharp, and suitable for drilling aluminum and other soft metals. Cobalt drill bits are more costly, but they are more durable and can penetrate through tough metals.
• Drill bit efficacy and durability are increased by coating. Titanium nitride (TiN) coating is frequently used for aluminum drilling because it reduces friction, heat, and attrition. Other coatings, including black oxide and zirconium nitride (ZrN), are appropriate for aluminum drilling.
• Angle of Point: The angle of the drill bit's point impacts its drilling performance. For aluminum drilling, it is recommended to use a drill bit with a point angle of 118 or 135 degrees. Drilling delicate metals requires a point angle of 118 degrees, while hard metals require a point angle of 135 degrees.
• The drill bit's particulate evacuation and coolant flow are determined by its flute design. A drill bit with a high helix angle and parabolic flute design is recommended for piercing aluminum. This design permits efficient chip evacuation and coolant flow, which prevents the material from overheating and dissolving.
• The diameter of the cavity to be drilled should correspond to the size of the drill bit. It is advised to use a smaller drill bit for pilot holes and to progressively increase the size until the desired diameter is reached.

---

Can I use a bit designed for wood to pierce aluminum?

No, wood drill blades are not suitable for aluminum drilling because they are designed to penetrate wood fibers, not metal. Using a wood drill bit on aluminum can damage the material and result in perforations that are less than precise.

Can I use a carbide drill bit for piercing aluminum?

Yes, carbide drill bits are appropriate for drilling aluminum due to their resistance to high temperatures and pressures. However, carbide drill blades are more expensive than their HSS and cobalt counterparts.

How do I stop aluminum from adhering to the drill bit?

Using a coolant or lubricant can prevent aluminum from adhering to the drill bit and reduce friction and heat. For aluminum drilling, you can use water, oil, or a specialized coolant/lubricant.

---

Aluminum must be drilled with the proper drill bit to ensure clear, precise holes without material damage. Consider the material, coating, point angle, flute design, and size when purchasing a drill bit for aluminum drilling. Using the proper drill bit and coolant/lubricant can improve the performance and durability of the drill bit, as well as prevent the material from overheating and dissolving.
