Products Description
PCD straight fluted drill overview
PCD Straight Fluted Drill
We manufacture a complete range of PCD (tipped or solid nib) drills and step drills for both rough hole processing and finishing cuts. We have developed a variety of pointed geometries to cover all possible applications when drilling pre-cast, through, or blind holes. However, there are still other factors to consider, such as hole depth, wall thickness, and interrupted or non-interrupted cuts.
This series uses tool bodies of particle degree carbide material. With this material, the PCD cutting edge can be sharper, and tool life and cutting quality are higher. The thermal conductivity of the tool is optimized; according to material features, we can design and improve the shape of the flute.

Frequently Asked Questions
Q What is a PCD straight fluted drill?
A PCD (Polycrystalline Diamond) straight fluted drill features diamond cutting edges tip-mounted or integrated as a solid nib. This straight-flute design ensures high centering accuracy and exceptional rigidity during drilling operations.
Q What materials are suitable for machining with these PCD drills?
They are highly optimized for drilling composite structures like CFRP, I/CFRP, and Ti/CFRP laminates. They are also ideal for non-ferrous metals (such as aluminum, magnesium, titanium, silicon), fiber materials, insulating materials, and specialized plastics.
Q Why is particle degree carbide used for the tool body?
Using particle degree carbide optimizes thermal conductivity and allows for a significantly sharper PCD cutting edge. This leads to higher cutting quality, increased tool stability, and extended overall tool life.
Q What factors should be considered when choosing a PCD drill geometry?
Key considerations include the hole depth, wall thickness of the workpiece, whether the cut is interrupted or non-interrupted, and whether you are processing pre-cast, through, or blind holes.
Q What are the lead times and standard packaging options?
Standard packaging includes a single protective box per wheel, with 10 to 20 wheels per master carton. Shipping takes between 3 to 30 days following order confirmation, subject to seasonal production demands and batch quantities.
