Drilling

Drilling is a service that cuts holes in bar, plate and fabricated parts. A Seller drills to the position and diameter the drawing gives. The work suits parts that need holes before assembly or finishing.

The part is set up and clamped on a drill or machining centre. The drill follows a marked position or a program. The hole can be drilled through or to a depth.

Steel, stainless steel, aluminium, brass and plastic are often drilled. Stainless steel and high tensile steel are harder on drill bits and need slower speeds. Aluminium and brass can be drilled quickly but can leave a built-up edge.

Ask about the largest hole diameter the machines can drill. Ask about the maximum depth to diameter ratio. Ask about the positional tolerance for hole patterns.
