Drills

Drills for electronics and fine mechanical work

When you work with small parts, enclosures and precision assemblies, the right drill bit and stable drilling setup matter more than raw power. In this category you will find drills and drill bits aimed at accurate results, especially for small diameters and delicate tasks.

Micro drill bits and precision drill sets

Micro drill bits are commonly used for small holes where alignment and surface finish are important. Many customers look for drill bits by exact diameter, so a micro drill bit set is often the easiest way to cover the most used sizes for repair, prototyping and model work.

Carbide vs HSS

• HSS micro drill bits: A practical all-round choice for many jobs in plastic and softer metals, and often more forgiving in less rigid setups.
• Carbide (tungsten carbide) micro drill bits: Very sharp and wear-resistant for high precision work, but more brittle and sensitive to side load and poor alignment.

Carbide is typically chosen for maximum precision and long life, while HSS is often preferred when the setup is simpler or when you want a bit that is less fragile.

Tips for cleaner holes and longer tool life

• Use stable clamping and keep the tool perfectly straight to avoid bending micro bits.
• Start gently and do not force the bit, especially in small diameters.
• Avoid side pressure with carbide bits to reduce the risk of snapping.
• Match speed and feed to the material and diameter to reduce heat and burrs.

Accessories that often make the difference

For micro drilling, a proper chuck or collet solution can improve control and reduce runout. If you drill very small diameters, consider a setup designed for precision work rather than a standard chuck.
