High Precision Drills in the UK

Precision drilling can be a tricky pursuit that places heavy demands on tools and operators alike. With such microscopic measurements and tight tolerances, there is often next to no margin for error so using the best possible equipment can make a huge difference in the resulting product.


A recent addition to our stock are through coolant drills from 1 mm to 3 mm diameter (in 0.1 mm increments) with drill depths from 5xD upto 30xD. These carbide coated drills offer a flexibilty and quality that is tough to beat. Also consider our larger diameter through coolant drills that range upto 10 mm diameter and 25xD in length.


With a range from 2 mm to 12 mm diameter these new flat-bottom drills have increased the capability to produce holes on angled or radial faces. Special size diameters can be produced to assist in eliminating hole drilling issues in your production.

Rainford Precision are official UK suppliers of high precision drills from several international manufacturers, which gives us access to a huge range of drills for a variety of specialised applications and operations. This formidable range, coupled with our team’s extensive knowledge of processes such as micro drilling and deep hole drilling, means that you can trust Rainford Precision to give you the perfect solution.

Drills for Composite Materials

An interesting addition to the range of drills available from Rainford Precision are micro drills for composite materials starting at 0.48 mm diameter. The importance of these new tools will open up lots of possibilities for composite material designers. The drills are available in two ranges, PCD and diamond coated.
