Diamond Glass Hole Chamfer Bit and Conical Countersink Tool

Flexible chamfering for small batches and local hole-edge repair

Small chamfer defects around a drilled glass hole can create disproportionate rework cost when the part must return to a fixed production station. For small batches and local correction, a compatible handheld chamfering setup can provide a flexible secondary operation without occupying the main drilling line.

The conical diamond profile is used to refine sharp hole edges, create a controlled bevel or countersink, and correct minor roughness after drilling. Actual cycle time depends on hole size, chamfer width, glass thickness, cooling, speed and operator technique rather than the tool alone.

Secure the glass on a soft, stable support, use continuous water cooling and start with light pressure at a controlled low speed. Inspect the hole for cracks before and after processing; severe drilling defects or structurally unsafe glass should not be treated as a simple cosmetic repair.
