Description
Wood-boring bits, also known as dowel drill bits, are widely used in cabinet and closet construction, hardware seating, and many other woodworking applications. As an ISO-certified manufacturer and supplier of dowel bits, Konetool offers a complete line of quality brad-point boring bits for global traders, distributors, wholesalers, and OEM suppliers.
Konetool TCT brad-point dowel drill bits are known for their long-lasting outstanding performance. They create accurate and tear-free holes in wood, laminate, and other wood composites. The non-stick coating helps the chips slide up and out of the hole, preventing residue accumulation. There is a height-adjusting screw at the end of the straight shank of our dowel drill bits, making Konetool dowel bits suitable for most boring machines such as Morbidelli, Koch, Torwegge, Koch, Shibaura, Balestrini, and Scheer. For our advanced technology, strict quality control, and 100% virgin raw material, Konetool is trusted by worldwide joinery, furniture, and display & sign makers.
Compared with our carbide-inserted brad-point dowel drill bit which has a small slice of tungsten carbide inserted into the drilling tip, our TCT brad-point dowel drill bit’s entire drilling tip is made of tungsten carbide. This design greatly enhances the drilling efficiency and service life of our TCT dowel bits. As is shown in the picture:

KONETOOL TCT Brad-point Dowel Drill Bit Features:
- Longer service time than Konetool standard carbide-tipped brad-point drill bits.
- Creating accurate and burr-free holes with smooth chip removal due to advanced flute design.
- Suitable for drilling blind holes without wandering.
- Both TCT and solid carbide brad-point dowel drill bits are offered.
- Cylindrical shank with a drive flat and adjustable top screw.
- Available in both left-hand and right-hand rotations.
Two types of TCT brad-point dowel drill bits, TCT brad-point dowel drill bit-Type A and TCT brad-point dowel drill bit-Type B, are provided by Konetool. The tip geometries of type-A bit and type-B bit are different, which are shown as follows:

In certain sizes, the type-B bits are also available as solid carbide boring bits. The cutting diameter of type-A bits ranges from 5mm to 15mm; the diameter of solid carbide type-B bits size from 3mm to 6mm and the diameter of TCT type-B bits size from 5mm to 15mm. The shank lengths are all 20mm.
