Hole saw / Cup Saw c.k tools 424002 19 mm cutting bit for metal and wood

The c.k tools 19 mm Cup Saw (cutting bit) is a single-diameter hole saw designed to cut clean circular openings in a range of materials including metal and wood. This compact 19 mm cutter is intended for use with compatible arbors or drill chucks and provides a practical solution for creating openings for pipes, conduit, wiring, fasteners and other installations where a precise small-diameter hole is required.

Advantages

The 19 mm cup saw is made for straightforward, repeatable cutting with a compact profile that reduces material waste. Its geometry and tooth design deliver efficient chip removal and stable cutting in both thin sheet metal and timber. The bit is simple to fit to standard arbors or chucks and is easy to remove and replace when carrying out multiple cuts. Its size makes it convenient for tight spaces and detail work where larger hole saws are impractical.

Suitable for

• Drilling small-diameter holes for piping and conduit
• Creating access holes for electrical wiring and cabling
• Installing small fasteners, bushings or grommets
• Service and repair tasks on metal panels and wooden components
• DIY projects requiring precise 19 mm circular cuts

Key specifications

• Cutting diameter: 19 mm
• Compatible materials: metal (thin sheet/plate) and wood
• Design: single-diameter cup saw / hole saw cutting bit
• Mounting: fits compatible drill chucks or hole saw arbors
• Application: manual or powered drilling with appropriate arbor and pilot bit

How to use

Select a compatible arbor or drill chuck and secure the 19 mm cup saw to the arbor according to the arbor manufacturer’s instructions. Where appropriate, fit a pilot bit to the arbor to guide the cut and improve accuracy. Position the cutter on the marked centre point, start the drill at low speed to establish the cut, then increase speed and apply steady, even pressure. For metal, use cutting lubricant to reduce heat and ensure smoother cutting; for wood, maintain steady feed to avoid splintering. After cutting, retract the cutter, remove any remaining slug and inspect the hole for burrs or rough edges.

Usage recommendations

Use appropriate personal protective equipment (safety glasses, gloves and hearing protection). Match drill speed and feed rate to the material being cut, use cutting fluid on metal to extend tool life, and ensure the arbor and pilot bit are correctly tightened before operation. Avoid excessive side loading and allow the tool to cool between prolonged cuts.
