CNC Wet Thin-Wall Crown / Wavy Tooth Diamond Core Drill Bit for Dekton® & Sintered Stone

Product Overview

Our CNC Wet Thin-Wall Crown / Wavy Tooth (波纹齿) Diamond Core Drill Bits are specially designed for precision hole drilling and cutting on Dekton®, sintered stone, ultra-compact surfaces, porcelain slabs and other hard engineered stone materials. The crown / wavy tooth cutting head is intended for applications that need an ultra-thin cutting profile and reduced material removal.

Designed for CNC wet cutting applications, these diamond core bits feature a thin-wall diamond cutting head that helps reduce cutting resistance and improve drilling efficiency.

The standard version is manufactured with an approximately 3mm thin wall. For applications requiring an ultra-thin cutting profile, the crown-tooth version can be manufactured with a wall thickness down to approximately 2mm.

Available with either a 1/2" GAS or M14 connection, these CNC diamond core bits can be manufactured in diameters from 5mm to 300mm according to customer requirements.

We provide customized and OEM diamond core bits for stone fabricators, countertop manufacturers, CNC tooling distributors, wholesalers, importers and professional stone processing companies.

Designed for Dekton® & Sintered Stone

Dekton®, sintered stone and other ultra-compact surfaces are extremely hard and dense materials that require specialized diamond tooling for efficient and controlled drilling.

Our CNC Wet Thin-Wall Diamond Core Drill Bits are developed specifically for professional stone fabrication applications where accurate hole dimensions, smooth cutting performance and controlled material removal are important.

The thin-wall diamond cutting head reduces the amount of material removed during drilling and helps minimize cutting resistance. This makes the tool particularly suitable for CNC wet drilling applications where cutting efficiency and hole accuracy are critical.

The standard version uses an approximately 3mm thin wall. For customers requiring an even thinner cutting profile, the crown-tooth version can be manufactured with a wall thickness down to approximately 2mm.

Cutting Head Options

Continuous Rim Diamond Core Bit

The continuous rim version features a continuous diamond cutting edge designed for smooth and controlled drilling of Dekton®, sintered stone, porcelain slabs and other hard and brittle materials.

The standard continuous rim version is manufactured with an approximately 3mm thin wall, providing a practical balance between cutting efficiency, cutting stability and tool strength.

Crown-Tooth Diamond Core Bit

The crown-tooth version is designed for applications requiring an ultra-thin cutting profile.

The wall thickness can be manufactured down to approximately 2mm, depending on the diameter and application requirements.

A thinner wall can reduce material removal during drilling, but the manufacturing process becomes more demanding as the wall thickness decreases. Therefore, the 2mm crown-tooth version requires higher manufacturing precision and normally has a higher production cost than the standard 3mm version.

Thin-Wall Design

The standard thin-wall diamond core bit is approximately 3mm thick.

For applications requiring a thinner cutting profile, the crown-tooth design can be manufactured with a wall thickness down to approximately 2mm.

The appropriate wall thickness can be selected according to the required hole diameter, material, CNC machine, cutting conditions and application requirements.

A 3mm wall provides a good balance between cutting efficiency, tool strength and manufacturing cost, while the approximately 2mm crown-tooth design is intended for applications where an ultra-thin cutting profile is required.

Available Connections

1/2" GAS Connection

The 1/2" GAS version is available for CNC machines and tool holders using a 1/2" GAS connection.

M14 Connection

The M14 version is available for CNC equipment and tooling systems using an M14 connection.

If you are not sure which connection is suitable for your CNC machine, send us your machine model, tool holder specification, drawing or a photo of your existing core bit. We can help confirm the appropriate connection before production.

Diameter Range: 5mm–300mm

We can manufacture CNC wet diamond core bits in diameters from 5mm to 300mm.

Small diameters are suitable for precision holes and smaller fabrication applications, while larger diameters can be used for countertop, sink, faucet, plumbing and other large-format hole cutting applications.

Custom diameters are available according to customer drawings, samples or specifications.

3mm Standard Thin Wall vs. 2mm Crown-Tooth

3mm Standard Thin Wall

The approximately 3mm thin-wall design provides a good balance between cutting efficiency, tool strength, manufacturing difficulty and cost.

It is suitable for many CNC wet drilling applications on Dekton®, sintered stone, porcelain slabs and other hard engineered stone materials.

2mm Crown-Tooth Thin Wall

The approximately 2mm version is designed for applications requiring a thinner cutting profile and reduced material removal.

Because the thinner the wall, the more difficult the manufacturing process becomes, the 2mm crown-tooth version requires higher manufacturing precision and tighter control during production.

As a result, the 2mm version normally has a higher manufacturing cost than the standard 3mm version.

Wet Cutting Performance

This CNC diamond core drill bit is designed primarily for wet cutting applications.

Water cooling helps control heat generated during drilling and supports stable cutting performance during CNC machining.

The appropriate cutting parameters should be selected according to the material, core bit diameter, CNC machine, spindle speed, feed rate, cooling conditions and diamond specification.

Customized Diamond Specifications

Different types of Dekton®, sintered stone, porcelain and ultra-compact surfaces may have different cutting characteristics.

The diamond specification can therefore be customized according to:

Material hardness

Material structure

Hole diameter

CNC machine

Spindle speed

Feed rate

Water cooling conditions

Required cutting speed

Required tool life

Production requirements

Our technical team can recommend a suitable diamond specification based on your material and application requirements.
