Drill Bits Set Evolution trepanation PREMIUM 6 pcs (EVO-WT-KPL-S) — core/drill cutters for metal and wood

The Evolution trepanation PREMIUM 6 pcs (EVO-WT-KPL-S) is a set of six core/drill cutters designed to cut larger diameter holes in common workshop materials. These trepans are intended for use with standard power drills and drill presses and are suitable for cutting through wood and a range of metals. The set contains a range of sizes to accommodate tasks such as creating openings for pipes, conduits, fittings, and other installations where precise circular holes are required.

Advantages

The set provides a compact selection of core cutters engineered for efficient material removal and reduced load on the drill. Each trepan is designed to produce clean, circular cuts with minimal tear-out in wood and controlled chip formation in metal. Compatibility with standard drill arbors and common drilling equipment allows straightforward installation and quick swapping between sizes. The kit supports a practical workflow when creating larger holes without excessive waste of material.

Suitable for

• Routing large-diameter holes in wood for pipes and cable passages
• Cutting openings in metal sheets and thin plates for fittings and conduits
• Installing fixtures that require precise circular openings
• Workshop and maintenance tasks using power drills or drill presses

Key specifications

• Quantity: 6 pieces (range of trepan diameters included)
• Intended materials: wood and common metals
• Compatibility: designed for use with power drills and drill presses
• Cut type: core cutting / hole saw (trepanation) for larger diameter holes
• Typical use: through-holes for pipes, conduits, fittings and fixtures

How to use

Fit the appropriate trepan to a compatible arbor or chuck and secure it according to the drill manufacturer's guidelines. Position the workpiece on a stable surface and mark the hole centre before starting. Begin drilling at moderate speed to establish the cut and apply steady, even pressure; adjust speed and feed depending on the material—slower speeds for metals and higher speeds for most woods. Clear chips regularly and, when cutting metal, use appropriate coolant or cutting lubricant to extend tool life and control heat. After cutting, deburr the hole edges if required.

Usage recommendations

Use personal protective equipment such as safety glasses and hearing protection. When cutting metal, secure the workpiece with clamps and use cutting fluid to reduce heat build-up. For cleaner holes in wood, back up the workpiece or use sacrificial backing to reduce tear-out. Match drill speed and feed to the material for best results.
