Fullerton Tool Company’s carbide drills deliver high machining accuracy even in difficult-to-cut materials, combining long tool life with minimal wear. Their ability to minimize burrs in composite materials helps reduce or even eliminate the need for secondary finishing operations.
This article introduces Fullerton’s carbide drills, which help lower the cost per hole by minimizing tool changes and post-processing time.

These carbide drills are ideal for manufacturers looking to reduce not only the purchase cost of cutting tools but also the overall operational cost associated with tool replacement and finishing steps. They are particularly well-suited for companies focused on improving efficiency.
In addition, the unique cutting edge geometry performs deburring and chamfering during the drilling process, significantly reducing finishing work.
These drills enhance both productivity and cost performance in mass production environments.
Note: Performance may vary depending on tool type, cutting speed, feed rate, coolant type, and machine rigidity.
The 1505-AP Dominator is a high-performance drill designed to cut even hard metals quickly and precisely.
Its standout feature is the double-margin design, which incorporates two guide margins along the drill’s sides. These margins support the drill body against the hole wall, reducing vibration and runout during machining to achieve consistently accurate hole dimensions.
The standard FC-7 coating provides excellent heat resistance and prevents edge wear, maintaining durability even when drilling tough materials such as stainless steel and heat-resistant alloys.
Thanks to its high hole accuracy, the 1505-AP Dominator can, in some cases, eliminate the need for a secondary reaming process, shortening production lead times and improving overall manufacturing efficiency.
The 1566-Poly Drill is engineered specifically for machining composite materials—such as carbon-fiber reinforced plastics (CFRP)—and resins.
To prevent fiber fraying and burr formation at the hole exit, the drill uses a unique “Burr Teeth” cutting-edge geometry.
This shears material cleanly rather than tearing it, maintaining surface quality.
By minimizing fuzz and burrs at the hole exit, the need for manual post-processing such as sanding or deburring is greatly reduced or even eliminated.
Special materials (plastic, rubber, carbon, etc.)
The 5566-MATRX Poly Drill builds upon the performance of the 1566-Poly Drill, offering enhanced wear resistance and significantly longer tool life.
It features an extremely hard base material, with an optional CVD diamond coating that dramatically improves wear resistance and extends tool life.
The combination of long-lasting sharpness and high durability not only reduces tool change frequency but also prevents breakout at the hole exit, ensuring consistent machining accuracy.
By minimizing burrs and fuzzing, the drill reduces the need for finishing operations and contributes to improved machine uptime and production efficiency.

Fullerton Tool Company offers a regrinding service for its carbide drills that have lost their sharpness through use.
This precision regrinding process restores the worn cutting edges to near-original performance, allowing the tools to deliver cutting results comparable to new ones.
Rather than discarding expensive tools after a single use, regrinding enables repeated utilization—significantly reducing the total cost per hole over the tool’s entire lifecycle.
By making effective use of existing equipment, manufacturers can achieve ongoing cost reductions and more sustainable operations.
