Holemaking-Drilling, Boring, Reaming
Huge range of solid & indexable drills from general purpose to ultra-high performance, as well as reamers, countersinks and boring systems.
HSS, Powder Metal and Carbide drills available for drilling all metals, ranging from general economy to high performance material-specific ranges.

Optimal outer & inner insert design and configuration reduces cutting loads by up to 50% whilst ensuring a better surface finish, and reduced vibration.
When it comes to hole making, selecting the most appropriate tooling and machining strategies for your application is critical. Therefore, we offer one of the industry’s most comprehensive selections of drills, reamers and boring tools. So, whether your focus is on volume, accuracy or cost savings, we have a tool that is perfect for your needs. Our applications experts can also help you identify the best tool for producing your desired hole size and quality in the most cost efficient and productive way possible.
Boring requires use of the right tool to achieve the desired hole characteristics of position accuracy, hole geometry and surface finish. Our extensive line of boring heads and bridge bars gives you right solution for your particular hole making applications. And when our standard boring product range meets its limits, we also offer custom boring solutions to meet your difficult machining challenges.
Step Drills
GTS manufacture Step Drills to the customers special requirements. These can be anything from a simple single step to much more complicated forms.
Step Drills are designed to do multiple jobs in a single pass. They are used to drill a hole with a counterbore, countersink, or chamfer or various steps in diameter in the hole. They can be re-sharpened or easily modified for a special length of step.
Reamers
We manufacture and also refurbish and recoat Insert style adjustable padded reamers either single or multiple diameter reamers made to customer requirements.
These reamers hold a tolerance of +0.003mm / -0.003mm size on Diameter and produce high accuracy and surface finish due to a burnishing effect of the pads.
The interchangeable blades give this reaming option an economical solution as against a solid reaming option.
We also offer highly competitive cost of replacement insert blades for existing Mapal and Sheffcut style reamers which you may be using at present.
We also supply and refurbish Multi-Bladed Brazed type solid head reamers, once again, coated to tolerances of +0.003mm / -0.003mm accuracy.
Multi-tooth design is normally required for higher feed rates per tooth to gain higher production levels and reduced cycle times which in turn gives higher profit margins or a more competitive production process for our customer base.
Often we work with customers to provide a service with our inserts to regrind/refurbish any inserts and tool holders that get damaged during machining operations and we can even buy your scrap carbide tooling.
