Features
TCT Solid Brad Point Boring Bits for Woodworking
Insert type row drill bit designed for high precision wood drilling applications.
High Quality Material & Craftsmanship
Micro-fine particle tungsten carbide cutting heads are adopted, paired with a low-temperature welding process. Engineered with excellent CNC grinding machinery to ensure high accuracy and production consistency.
Superior Impact Resistance
The marking edge of the drill tip adopts a negative relief angle design, which greatly increases structural strength and enhances impact resistance during operation.
Clean & Efficient Results
Enables high-efficiency drilling processes without edge explosion or burning, resulting in perfectly shaped, smooth holes with clean finishes.
Application
Applicable Machines
TCT Solid Brad Point Boring Bits are compatible with row drilling machines, bench drill machines, electric drill machines, impact drill machines, CNC engraving machines, and other standard boring equipment. Please select the correct tool model based on your machine's shank compatibility.

FAQ
What are TCT Solid Brad Point Boring Bits used for?
They are specialized boring tools designed for woodworking, particularly for drilling clean blind holes. They are ideal for high-precision operations in panel furniture production, compatible with CNC routers and row drilling rigs.
What materials can these drill bits process?
They can process a wide range of wood materials, including MDF (medium-density fiberboard), particle board, multi-layer board, plywood, melamine boards, painted boards, bamboo, and solid wood.
What is the difference between Left (L) and Right (R) rotation?
Woodworking multi-spindle row drilling machines use alternating rotating spindles to balance torque. Spindles rotate in opposing directions, which is why boring bits are offered in both left-hand rotation (typically black or orange color-coded) and right-hand rotation (typically black or red color-coded) to match the machine spindles.
What are the benefits of Tungsten Carbide tips (TCT)?
Tungsten Carbide offers exceptional hardness, high heat resistance, and excellent wear resistance compared to standard high-speed steel (HSS). It keeps the cutting edges sharp for a longer period, resulting in clean cuts, less burning, and a longer tool life.
Why do these bits prevent edge cracking during drilling?
The marking edges of the drill tip utilize a negative relief angle design. This design feature reinforces the cutter tip, increases overall impact resistance, and scores the circumference of the hole before the main blade clears the material, ensuring smooth, burst-free edges.
What machines are compatible with these bits?
These boring bits are compatible with row drilling machines, bench drill presses, CNC engraving routers, and other boring equipment. Please ensure the machine chuck size matches the 10mm shank diameter of these bits.
