Applications
for Fullerton Tool

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.

How to Choose Carbide Drills from
Fullerton Tool Company

As a carbide drills manufacturer with high-performance options for metals and composite materials, Fullerton Tool Company offers drill series designed for accuracy, burr control, wear resistance, and production efficiency. The right choice depends on the workpiece material, required hole accuracy, exit-hole quality, tool life expectations, and whether secondary finishing operations need to be reduced.

For High-Accuracy Drilling in Tough Metals

Recommended Series

1505-AP Dominator

When to Choose This Type

Choose the 1505-AP Dominator when drilling tough metals where hole accuracy, vibration control, and tool life are important. This high-performance drill is suitable for applications that require precise hole dimensions in materials such as stainless steel, heat-resistant alloys, cast iron, and other demanding workpieces.

Its double-margin design uses two guide margins along the drill body to support the tool against the hole wall. This helps reduce vibration and runout during machining, supporting more consistent hole size and improved dimensional accuracy.

The standard FC-7 coating provides heat resistance and helps reduce cutting-edge wear, maintaining durability during hard-metal drilling. Because of its high hole accuracy, the 1505-AP Dominator may, in some cases, reduce or eliminate the need for a secondary reaming process, helping shorten lead times and improve manufacturing efficiency.

For Composite Materials and Burr Reduction

Recommended Series

1566-Poly Drill

When to Choose This Type

Choose the 1566-Poly Drill when machining composite materials such as CFRP, plastics, resins, and other special materials where burrs, fuzzing, or fiber fraying can occur at the hole exit. This series is designed to maintain clean hole quality and reduce the need for manual finishing after drilling.

The drill uses a unique “Burr Teeth” cutting-edge geometry that shears the material cleanly rather than tearing it. This helps minimize burr formation, fiber breakout, and surface damage around the hole exit.

By reducing fuzz and burrs, the 1566-Poly Drill can help limit or eliminate post-processing operations such as sanding or deburring, supporting more efficient composite-part production.

Suitable Materials

Special materials, including plastic, rubber, and carbon.

Available Diameters

• 5.00 mm, approximately 0.197"

• 11.50 mm, approximately 0.453"
• 12.00 mm, approximately 0.472"

For Longer Tool Life in Composite Drilling

Recommended Series

5566-MATRX Poly Drill

When to Choose This Type

Choose the 5566-MATRX Poly Drill when drilling composites and other abrasive special materials where longer tool life, consistent edge sharpness, and reduced tool change frequency are priorities. This series builds on the 1566-Poly Drill concept with enhanced wear resistance for higher-volume or more demanding composite machining.

The drill features an extremely hard base material, with an optional CVD diamond coating available for dramatically improved wear resistance. This helps maintain sharpness over longer production runs and supports consistent hole quality.

By helping prevent breakout at the hole exit and minimizing burrs and fuzzing, the 5566-MATRX Poly Drill can reduce finishing operations, improve machine uptime, and support more stable production efficiency.
