If you're looking for high-quality drill bits for working with stainless steel, then long length bits are a great option to consider. These bits are designed to be longer than standard drill bits, which makes them ideal for drilling through thicker pieces of metal. They are also made from durable materials that can withstand the heat and pressure that comes with drilling through tough materials like stainless steel. With their sharp cutting edges and precise design, long length bits can help you achieve accurate and clean holes in your metalwork. So, if you're looking to tackle a stainless steel project, investing in a set of long length bits could be a wise choice.

Frequently Asked Questions (FAQs)

1. How long can you get a drill bit?

Bit size reflects the diameter of the body. Some projects call for specific drill bit sizes, but a bit set that includes sizes from 1/16 inch to 1/4 inch will work for many jobs around the home and workshop. You can add larger bits — 5/16-inch, 3/8-inch, 7/16-inch and 1/2-inch bits — if you need them.

2. What is a HSS drill bit?

HSS drill bits, an acronym for high speed steel drill bits are extremely hardwearing and particularly well designed for drilling into metal surfaces, as they are much more resistant to the heat generated from the fast speed operation. The front edges cut the material, whilst the spirals remove debris from the hole.

3. What is TCT drill bit?

The Irwin Metric TCT (Tungsten Carbide Tipped) Drill Bits offer precision drilling with stationary machines in hardened steel, cast iron, bronze alloys and manganese alloyed steel. ... A coolant should always be used when drilling with TCT twist drill bits.
