The set includes 5 mm, 6 mm and 8 mm diameters with a 1/4" (6.3 mm) shank suitable for standard chucks.

## Long description

ALPEN Glas ATM 3 is a three-piece drill bit set created for precise drilling in glass and other brittle materials. The set contains bits with diameters 5 mm, 6 mm and 8 mm, each fitted with a 1/4" (6.3 mm) shank compatible with common cordless and corded drills that accept hex or standard chucks. The bit geometry and cutting edges are designed to provide controlled material removal on glass panes, tiles and ceramics when used at low speed with light feed and cooling.
Advantages
The ALPEN Glas ATM 3 set offers clean hole cutting in brittle substrates thanks to cutting-optimized tip geometry that reduces chipping and cracking. Standard 1/4" (6.3 mm) shanks ensure simple tool changes and compatibility with a wide range of drills. The three most common glass hole diameters are included to cover small installation and repair tasks without the need to buy single bits separately.
Suitable for
Drilling holes in annealed and tempered glass (with appropriate technique)
Creating openings in ceramic tiles and porcelain
Installing fittings, handles or fixtures in glass or glazed surfaces
Repair and installation work on glass panes, mirrors and decorative panels
Key specifications
Set composition: three drill bits
Working diameters: 5 mm, 6 mm, 8 mm
Shank type and size: 1/4" (6.3 mm) shank suitable for standard chucks
Material compatibility: glass, glazed ceramics, tiles and other brittle materials
Recommended operating mode: low rotational speed, light feed and continuous cooling
How to use
Secure the workpiece flat and prevent movement or vibration. Mark the drilling point and, if possible, support the glass from the reverse side to reduce stress. Fit the chosen ALPEN Glas ATM 3 bit into the drill chuck and set the drill to a low speed. Begin drilling with light, steady pressure; do not force the bit. Apply a continuous coolant such as water to the cutting area to keep the bit and glass cool and to wash away debris. After penetration, release pressure and withdraw the bit slowly while the drill is still rotating to avoid chipping the exit surface.
Usage recommendations
Use appropriate personal protective equipment (safety glasses, cut-resistant gloves) and work on a stable surface. For best results, practice on a scrap piece of the same material to confirm speed, pressure and cooling. For thicker or tempered glass, consider professional methods or specialist tools and avoid excessive force that can cause cracking.
