A versatile tool used for rivet hole prepping – Available in HSS Cobalt or solid carbide
These straight shank piloted countersinks are used regularly by Airbus, Rolls Royce, Mclaren F1, Lotus F1, Williams F1 and many more.
An extremely versatile tool which is designed predominantly for preparing an existing hole for riveting, but also used for precise
countersinking when the extra support of a pilot is required. These popular tools are also known as a ‘stem’ or ‘open’ countersinks.
Supplied in 90º, 100º and 120º as standard with other angles such as 82º available on request with little increase in price or lead time.
See page 8, 9 and 10 of our catalogue for more information
A fantastic tool for fast and precise deburring of holes – HSS Cobalt
The optimum tool for small chamfering or edge breaking operations. Well suited to both hand held or machine fed. A comprehensive range of
sizes up to 35mm and angles from 60 to 100 degrees are available as standard. See page 20 and 21 of our catalogue for more information
A multi-flute general purpose countersinking tool.
These are manufactured in HSS Cobalt and precision ground to our usual high standards. Suitable for highspeed countersinking in materials
such as wood, plastic and aluminium. See page 24 and 25 of our catalogue for more information
A wide variety of metric and imperial HSS Cobalt Counterbores
A popular choice for recessing predrilled holes to suit cap head screws. We have adopted the successful positive rake flute geometry with
a curved and smooth finish to aid chip removal. Our standard range covers most standard cap screw sizes. See page 26 and 28 of our catalogue
for more information
The precision ground morse taper fits directly into a machine spindle for extra rigidity. Available from 16mm to 80mm diameter and 60 or 90
degrees. See page 23 of our catalogue for more information.
Microstop Piloted HSS Cobalt Countersinks with Integral or Removable Pilot
Microstop piloted countersinks when used with a microstop cage can be adjusted to the required depth in increments of 0.001”.
Widely used within the aerospace industry to aid the huge task of countersinking the millions of holes to produce an aircraft.
These tools come with standard corner radius’ to form a precise rounded edge between the countersink angle and the pre-drilled hole.
The standard corner radius’ have been chosen to suit common aircraft rivets. However, our specialist machinery enables us to produce
any angle and corner radius to suit more bespoke applications. We supply these with metric or imperial threads to suit all common
microstop cages. See page 11 and 12 of our catalogue for more information
Supplied in 90º, 100º and 120º as standard with other angles such as 82º available on request with little increase in price and
lead time.
Cages are also available for purchase on request
Replacement Pilots
A large range of pilots are available to suit all of our cutters. They are finish ground to order so just tell us the pilot size
required and the cutter it needs to fit in to and we can supply.
Specials, variations to standards and related products.
We can modify existing standard products to suit special requirements, be that an odd angle or a non standard diameter. We also
