Introduction to Glass Drilling Technology
What is Glass Drilling?
Glass drilling is the process of creating precise, clean holes through a glass panel to accept hardware, fittings, or fixing door handles and locks, hinges, standoffs, curtain-wall brackets, and appliance mounting points. Because a drilled hole removes material from the glass, it becomes the single highest-stress point on the panel.
Why precision matters
Hole diameter, position, and edge distance must be held to tight tolerance — industry practice keeps edge distance at roughly twice the hole diameter, with drilling performed from both faces to prevent exit-side chipping. Any deviation becomes a crack-initiation point once the glass is tempered or put under load.
Modern factories rely on CNC-guided and laser drilling systems to meet these requirements at production speed — automation removes manual marking error, holds accuracy consistently across large batches, and keeps breakage rates low even on large architectural panels.
Structural Safety
Correct hole size and edge distance prevent stress cracks before and after tempering.
Hardware Compatibility
Precise diameters and positions ensure hinges, locks and fittings seat correctly.
Production Speed
CNC and multi-spindle systems drill batches in a fraction of manual processing time.
Repeatable Accuracy
Automated positioning holds tolerance consistently from the first panel to the last.
Glass Drilling Production Flow
Glass Loading
Cut and edged sheets fed onto the drilling table
Positioning
Sheet aligned to programmed hole coordinates
Drilling
Spindles drill from one or both faces to size
Inspection
Hole diameter, position and finish checked
Washing
Panel cleaned of glass particles and coolant
Further Processing
Sent to tempering, laminating or assembly
One continuous, inspection-gated flow
Why this sequence matters
Inspection between drilling and washing catches out-of-tolerance holes before the panel moves further down the line — far cheaper than discovering a defect after tempering. Washing then removes all glass dust and coolant residue, which would otherwise interfere with lamination, coating, or sealant adhesion in later stages.
Integrating drilling directly into a cutting-edging-drilling-washing line, rather than running it as an isolated station, keeps handling to a minimum and reduces the breakage risk that comes with repeatedly moving large glass panels.
Drilling Methods & Hole Types
Drilling Methods
Diamond-Core Drilling
Diamond-tipped hollow core bits — the industry-standard method. Typical accuracy ±0.10–0.15mm.
CNC-Guided Drilling
Computer-controlled spindle positioning drills multi-hole patterns automatically. Tightens accuracy to about ±0.05mm.
Laser Drilling
Non-contact focused laser (e.g. MOPA fiber) for thin, coated or solar glass, with edge chipping as fine as 0.25–0.4 microns.
Typical Process Parameters
Glass drilling generally runs spindle speeds of roughly 3,000–8,000 RPM with continuous water-coolant flow to control heat and flush debris. Thin substrates (under 2mm) call for higher speed and lighter feed pressure; glass over 6mm needs slower speed and more coolant to manage heat buildup.
Common Hole Types
Standard Round Hole
The most common type, for handles, hinges and standoffs.
Countersunk Hole
Angled recess lets screw heads sit flush with the glass surface.
Elongated / Slotted Hole
Allows adjustment tolerance in bracket and fixing alignment.
Large-Diameter Hole
For appliance ports, handrail posts and cable pass-throughs.
Glass Drilling Applications
Precision-drilled glass is required across nearly every branch of architectural, furniture, and consumer glass manufacturing.

CNC Glass Drilling Machine
Automatic CNC-controlled drilling for standard production runs and batch hole programs — dual drilling heads, servo-driven positioning and PLC + touch screen control for high-volume factory production lines.
Automatic Glass Drilling Machine
Streamlined automatic drilling built for high-volume factory production lines — conveyor belt automatic feeding, dual drilling heads with AC servo X/Z/W 3-axis positioning, and PLC + touch screen control.
Double Heads Big Hole Drilling Machine
Simultaneous dual-hole processing for large-diameter appliance and handrail glass holes — two pairs of upper and lower spindles drill Φ50–Φ230mm holes through 6–15mm glass at ±0.30mm accuracy.
HANWIN builds its drilling series on the same CNC control, servo positioning, and water-cooled spindle technology used across its Cutting and Edging Series. For detailed model-specific technical drawings and configuration options, please request the latest HANWIN Drilling Series datasheet.
CNC vs. Traditional Drilling
Moving from manual drilling to CNC automation removes operator dependence, shrinks cycle times, and delivers identical hole quality on every panel.
| Factor | Traditional / Manual Drilling | CNC / HANWIN Automated Drilling |
|---|---|---|
| Accuracy | ±0.10–0.15mm, operator-dependent | Down to ±0.05mm, program-controlled |
| Efficiency | Single hole at a time, slow setup | Multi-hole programs, continuous cycle |
| Labor | Skilled operator required per machine | One operator can oversee multiple lines |
| Repeatability | Varies between operators and shifts | Identical results across every panel |
| Maintenance | Frequent bit changes and manual checks | Automated monitoring, scheduled service |
| Quality | Inconsistent edge chipping risk | Clean, consistent holes with dual-face drilling |

Production Line Integration
One continuous conveyor path
Integrating drilling into a full processing line
HANWIN drilling machines are designed to sit between the edging and washing stations of a complete line, matching the conveyor height, control interface, and glass-handling logic of HANWIN's Cutting and Edging Series. This keeps panels moving on a single continuous conveyor path rather than being manually lifted between stand-alone machines.
For factories running mixed production — some panels requiring holes, others not — the drilling station can be configured as a bypass point on the line, so undrilled panels pass straight through to washing without a separate handling step.
