Drill bit for glass and ceramics MODECO MN-61-204, carbide, 4 mm, 10 pcs

Carbide drill bits MODECO MN-61-204 are a set of ten 4 mm diameter cutting tools designed for drilling glass and ceramic materials. Each bit is manufactured from hard carbide to provide a precise cutting edge and increased wear resistance when working on brittle surfaces. The set is intended for use with hand drills or drill presses at low rotational speeds and is suitable for tasks such as installing fittings, making holes in tiles, preparing glass fixtures and carrying out DIY repairs where controlled, clean holes are required.

Advantages

Carbide construction ensures a sharp, durable tip that maintains cutting performance over repeated use on hard, brittle materials. The 4 mm diameter is suitable for common fixing and mounting applications while the consistent geometry of each bit promotes accurate, clean holes with reduced chipping. Supplied as a set of ten, the kit offers immediate replacements for professional or home projects and reduces downtime due to worn tips.

Suitable for

• Drilling holes in glass panes and mirrors
• Cutting through ceramic tiles and sanitaryware
• Preparing anchor and fixing points for fittings
• Small renovation and DIY repair tasks that require precise holes

Key specifications

• Material of cutting edge: carbide
• Nominal diameter: 4 mm
• Quantity in set: 10 pieces
• Recommended drilling speed: low RPM (use slow feed and light pressure)
• Compatible machines: hand drills and drill presses

How to use

Mark the drilling point and secure the workpiece to prevent movement. Fit a 4 mm carbide bit into the drill chuck and set the machine to a low speed. Begin drilling with light, steady pressure, keeping the bit perpendicular to the surface. For glass and glazed ceramics, consider starting the hole at an angled position briefly to create a small groove, then straighten the drill as the bit engages. Use intermittent drilling and withdraw the bit periodically to clear debris and avoid overheating. If available, apply water as a coolant/lubricant to reduce heat buildup and improve hole quality.

Usage recommendations

Use personal protective equipment such as safety glasses and gloves, clamp the workpiece securely, and avoid excessive force or high speed; these precautions extend bit life and reduce the risk of cracking brittle materials.
