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.
