About Us
BSA Regal Cutting Tools specialise in the manufacture
of the well established Robert Charles brand of high
quality Countersinks and Counterbores.
We are the sole manufacturer of Robert Charles
branded tools which, over the past 35 years, have
earned their enviable worldwide reputation in the
demanding aerospace, automotive, marine and
general engineering industries.
Robert Charles’ founding principle was to specialise in
Countersinks and Counterbores to produce the best
available performance.
We remain unconditionally faithful to this principle since
acquiring the Robert Charles brand in early 2009.
BSA Regal Cutting Tools continues to supply the same
high quality tools using only the best quality M35 and
M42 high speed steel alloy with cobalt. The cobalt
content of M35 and M42 (5% and 8% respectively)
gives increased ‘Hot Hardness’ extending tool life with
faster cutting speeds and feeds.
Next day deliveries of standard tools are usually
available from our extensive stock with specials taking
a few days longer.
BLOODHOUND SSC
product sponsor
The Car
Bloodhound SSC is exactly what it says - a SuperSonic
Car! It is supersonic because it is designed to go faster
than the speed of sound.
It is a car because it has four wheels and is under full
control of its driver.
It has a slender body of approximately 14m length with
two front wheels within the body and two rear wheels
mounted externally within wheel fairings.
Bloodhound SSC is a jet and rocket powered car
designed to go at 1,000 mph (just over 1,600 kph). It
weighs over 7 tonnes and the engines produce more
than 135,000 horsepower - more than 6 times the power
of all the Formula 1 cars on a starting grid put together!
The Car is a mix of car and aircraft technology, with the
front half being a carbon fibre monocoque like a racing
car and the back half being a metallic framework and
panels like an aircraft.
Our Sponsorship
We were initially approached by the BLOODHOUND SSC Build Lead Engineer Chris Dee who had used our tools
before during his time with theArrows Formula 1 Team. Our tools are required for countersinking the tens of thousands
of holes on the car in preparation for riveting.
We are proud to be the number one choice for this vital part of the build and even prouder to be product sponsoring
this project.

100% of our range is available to be Titanium Nitride
coated(TiN). TiN coating offers the following benefits:
 LONGER TOOL LIFE
 IMPROVED CUTTING EDGE RETENTION
 REDUCED FRICTION/INCREASED LUBRICITY
 HARDER CUTTING SURFACE
 FASTER CUTTING SPEEDS
 COSMETICALLY APPEALING
ORDERING INFORMATION
Please call for current prices and lead times. A minimum
order value of £30 net applies.
These are used with our threaded shank
countersinks and allow the engineer to adjust the
depth of the countersink in 0.001” increments.
Predominantly used in the aerospace industry for
rivet preparation, they are also very useful in
general engineering applications.
ORDERING INFORMATION
Available in various sizes to suit various threads
e.g. M6 x 1, M8 x 1 and 1/4” UNF.

  • 4. About Us BSA Regal Cutting Tools specialise in the manufacture of the well established Robert Charles brand of high quality Countersinks and Counterbores. We are the sole manufacturer of Robert Charles branded tools which, over the past 35 years, have earned their enviable worldwide reputation in the demanding aerospace, automotive, marine and general engineering industries. Robert Charles’ founding principle was to specialise in Countersinks and Counterbores to produce the best available performance. We remain unconditionally faithful to this principle since acquiring the Robert Charles brand in early 2009. BSA Regal Cutting Tools continues to supply the same high quality tools using only the best quality M35 and M42 high speed steel alloy with cobalt. The cobalt content of M35 and M42 (5% and 8% respectively) gives increased ‘Hot Hardness’ extending tool life with faster cutting speeds and feeds. Next day deliveries of standard tools are usually available from our extensive stock with specials taking a few days longer. BLOODHOUND SSC product sponsor The Car Bloodhound SSC is exactly what it says - a SuperSonic Car! It is supersonic because it is designed to go faster than the speed of sound. It is a car because it has four wheels and is under full control of its driver. It has a slender body of approximately 14m length with two front wheels within the body and two rear wheels mounted externally within wheel fairings. Bloodhound SSC is a jet and rocket powered car designed to go at 1,000 mph (just over 1,600 kph). It weighs over 7 tonnes and the engines produce more than 135,000 horsepower - more than 6 times the power of all the Formula 1 cars on a starting grid put together! The Car is a mix of car and aircraft technology, with the front half being a carbon fibre monocoque like a racing car and the back half being a metallic framework and panels like an aircraft. Our Sponsorship We were initially approached by the BLOODHOUND SSC Build Lead Engineer Chris Dee who had used our tools before during his time with theArrows Formula 1 Team. Our tools are required for countersinking the tens of thousands of holes on the car in preparation for riveting. We are proud to be the number one choice for this vital part of the build and even prouder to be product sponsoring this project. CLICK FOR CONTENTS
