75mm/95mm Sintered Solid Diamond Drill Bit - Customizable Height
for Precision Glass Drilling
In the demanding field of glass deep processing, the quality of
drilling tools directly determines product yield, processing
efficiency, and surface finish. Our 75mm or 95mm height sintered
solid diamond drill bit is engineered to address the core pain
points of glass drilling—fragility, precision requirements, and
diverse processing needs.
Sintered Solid Diamond: The Core of Superior Performance
The drill bit adopts a full-body sintering process, where
high-purity industrial diamond particles (particle size 30-50μm)
are tightly bonded with a copper-tin alloy matrix through
high-temperature (1100℃) and high-pressure (20MPa) sintering.
- Ultra-high hardness (HV 10000+, 10 times that of carbide) enables
effortless cutting through various glass types
- Excellent wear resistance reduces tool wear to less than 0.02mm per
100 holes
- Good thermal conductivity dissipates drilling heat rapidly,
avoiding thermal cracks
Precision Drilling: Guaranteeing Consistent Quality
Our drill bit achieves industry-leading precision through two key
designs:
- 75mm diameter drill tip features ground spiral flute structure for
reduced drilling resistance
- Hole diameter tolerance controlled within ±0.05mm
- Concentricity of drill shank and drill tip less than 0.03mm
In application tests, the drill bit maintains stable performance at
800-1500rpm, drilling 300+ holes on 12mm thick tempered glass
continuously without performance degradation.
Customizable Height & Broad Application Adaptability
We offer customized height services ranging from 50mm to 200mm to
adapt to various drilling depths and equipment structures. The
customization cycle is as short as 3 working days.
Compatible with mainstream glass drilling equipment from brands
such as Bottero, Intermac, and Biesse. Applications include:
- Automotive glass (sunroof hole drilling)
- Architectural glass (curtain wall fixing hole drilling)
- Furniture glass (tabletop installation hole drilling)
Reliable After-Sales & Cost-Efficiency
Each drill bit undergoes 12 quality inspection procedures. We
provide a 3-month quality guarantee with free replacement for
non-human damage during normal use.
Compared with imported similar products, our drill bit has a 20%
lower price while maintaining equivalent performance, helping
reduce processing costs and enhance market competitiveness.
