CUSTOM CARBIDE DRILL

Solid carbide twist drills are cutting tools used to form round holes in work pieces.
——
Solid Carbide Spiral Drill Bits are compact in design and typically feature a helical cutting edge,

which helps to distribute the cutting forces, thereby reducing the stress on the workpiece and extending the life of the tool.
Their superior infusion design and cutting geometry allows for a smoother drilling process,

enabling precise round holes to be created in the workpiece.

Drill Production Process

Carbide drill bits are drilling tools made of tungsten carbide material. They offer the best combination of penetration and precision.

——

● The new flute shape takes into account the lightness of the cutting edge, the rigidity of the tool and the chip space.
● Professional after treatment for coating ensures low-resistance high-efficiency machining.
● High quality tungsten carbide rod，DIN6537 fixed shank alloy drill bit, as long as it is within the specification range, the shank diameter is the same, saving the cost of the drill chuck.

Drill Diameter

Drills come in different diameters for different hole sizes and depths.

In general, drills with smaller diameters are more widely used. According to the size and specification of the drill bit, there are micro-diameter drill bits/3D/5D/8D. Wide chip flute for improved chip evacuation,Corrugated blade type for finely breaking chips.

Small Carbide Drill Bits-Dia1-2.9mm

Small carbide drill bits with diameters ranging from 1mm to 2.9mm are precision cutting tools designed for drilling small holes with exceptional accuracy and performance. These miniature drill bits are crafted from high-quality carbide material, renowned for its hardness, wear resistance, and durability.

Micro Carbide Drill Bits 3D-Dia1-20mm

The length of a 3D Micro Diameter Drill Bit is three times its diameter. This means that a 3D microbore drill is required when the depth of the hole is three times the diameter of the drill. This type of micro-diameter drill is suitable for applications where relatively shallow micro-holes are required, such as in electronics, medical devices and micromechanics.

Micro Carbide Drill Bits 5D-Dia1-20mm

5D Micro Diameter Drill Bits are five times longer than their diameter. This type of micro-diameter drill bit is suitable for relatively deep micro-holes, such as those used in aerospace, automotive manufacturing and oil exploration applications. Due to their greater length, 5D Micro Bore Drills may require more consistent and precise machining equipment to ensure hole quality and accuracy.

Micro Carbide Drill Bits 8D-Dia3-20mm

The 8D Micro Diameter Drill Bit is eight times longer than its diameter. This is a micro-diameter drill bit for deep hole drilling tasks, often used in specific applications where deeper hole depths are required. These applications may include certain aerospace components, micro-hole assemblies for medical devices, and more.
