Guide for the master: how to choose a reliable metal drill

Metal drills are an important type of consumables for tools actively used both in everyday life and industry. The correct choice affects not only accuracy and processing speed, but also the safety of working with the tool. An incorrectly selected drill can break, damage the part, or even the tool itself. That is why it is important to choose high-quality professional metal drills that meet operating conditions. At the VADA store, you can buy metal drills with a quality guarantee, at an affordable price, and with delivery throughout Ukraine.

What are metal drills?

Metal drills are cutting tools used to create holes in metal surfaces. Their main task is to accurately, efficiently, and safely drill a hole in solid material.

For manufacturing such drills, the following materials are used:

• High-speed steel (HSS) — a universal option for ferrous and non-ferrous metals.
• Cobalt alloys — suitable for working with stainless steel and hard alloys.
• Titanium or nitride coating — reduces friction, increases wear resistance, and prevents overheating.

Drills are suitable for ferrous metals (steel, cast iron), non-ferrous alloys (aluminum, copper), and stainless steel. Professional metal drills are characterized by precise sharpening, strength, and durability. Unlike household drills, they withstand higher loads and have better heat resistance.

Types of metal drills

There are several basic types of drills for metalworking:

• Classic spiral drills — the most common, suitable for most tasks, with a standard shape and wide application.
• Step drill — allows making holes of different diameters in thin metal sheets; convenient when multiple hole sizes are needed without changing tools.
• Crown drill — used to create large holes; has a serrated shape, drills with less effort while preserving material integrity.

Professional metal drills can have titanium, cobalt, or oxidized coatings. Titanium drills last longer by significantly reducing friction. Cobalt drills cut hard metals better. Oxidized drills have a black coating and improve heat resistance.

Each type has advantages, so choosing depends on your tasks.

How to choose a metal drill?

Choosing the right metal drill requires a comprehensive approach. Pay attention to these parameters:

• Material to be processed: aluminum, steel, stainless steel — optimal options exist for each.
• Tool type: some drills suit hand drills, others drilling machines.
• Frequency of use: basic sets for home users; reinforced options for professionals.
• Coating: titanium or cobalt coatings significantly extend service life.
• Sharpening angle and shape: determines how easily the drill penetrates material.
• Hole diameter and drill length: depend on the specific task.

After determining your tasks, you can easily buy consumables for tools at the VADA store — with professional advice and a quality guarantee. To ensure long-term use of metal drills, follow these tips:

• Avoid overheating — work at medium speeds.
• Use lubricant when drilling hard metals.
• Store drills in a dry place, preferably in a case.

Common mistakes include using drills for unintended purposes, incorrect fastening in the chuck, and excessively high speeds.
