## Summary description

Irwin 4 mm carbide drill bit designed for drilling glass and ceramic tiles. Cylindrical shank and carbide tip provide precise cutting and wear resistance when working with brittle materials. Suitable for use with hand drills at low to medium speed for installing fixtures, tiling jobs, bathroom and kitchen fittings, and other tasks requiring clean holes in glazed surfaces.

## Long description

Irwin 4 mm carbide drill bit with a cylindrical tip is designed for drilling glass and ceramic tiles. The 4 mm diameter and carbide cutting tip enable precise perforation of brittle glazed surfaces while the straight shank ensures stable seating in standard drill chucks. Intended for low to medium speed drilling, this bit is applicable when clean, chip-free holes are required for fixtures, fittings and installation tasks in bathrooms, kitchens and tiling work.
Advantages
The carbide tip offers high hardness and wear resistance suited to abrasive glazed materials, reducing tip deformation and maintaining cutting performance over multiple holes. The cylindrical shank provides reliable grip in hand drills and guarantees concentric rotation for accurate hole placement. The small 4 mm diameter allows for neat, compact holes for anchor pins, screws and small fittings without cracking surrounding tiles when used correctly.
Suitable for
 Drilling holes in glass panes and glazed ceramic tiles
 Installing bathroom and kitchen fittings where clean, small holes are needed
 Mounting fixtures that require 4 mm openings for anchors or screws
 Repair and tiling tasks on brittle or glazed surfaces
Key specifications
 Diameter: 4 mm
 Tip material: carbide
 Shank type: cylindrical (straight) shank
 Recommended speed: low to medium RPM
 Suitable materials: glass, glazed ceramic tiles
How to use
Secure the workpiece and mark the drilling position. Use a hand drill with adjustable speed, set to low or medium RPM to avoid overheating and cracking. Start drilling with light steady pressure; keep the bit perpendicular to the surface and allow the carbide tip to score the glaze before increasing pressure. For glass, consider supporting the opposite side or using masking tape over the drill point to reduce chipping. Withdraw the bit periodically to clear debris and cool the tip if necessary.
Usage recommendations
Use water spray or intermittent drilling to reduce heat buildup when drilling multiple holes. Avoid high-speed drilling and excessive pressure to prevent cracking in brittle materials. For larger fasteners, first drill a pilot hole with this 4 mm bit and then proceed with appropriately sized bits or anchors as required.
