Hole saw set Delphi Tools OTWORNICE Holedozer Quicklock — 9 pieces

Delphi Tools OTWORNICE Holedozer Quicklock — 9 pieces is a hole saw set designed to cut circular openings in materials such as wood, plastics and some soft non-ferrous metals. The set includes a selection of diameters and a Quicklock connection system that enables quicker exchange of pilot bits and saw cups when used with compatible drills and drivers. It is intended for installation and maintenance tasks where controlled round penetrations are required.

Advantages

The Quicklock connection reduces downtime by simplifying bit and cup changes without additional tools. Hardened cutting edges provide a clean cut in wood and common plastics while the set’s range of diameters covers typical needs for plumbing, electrical and HVAC penetrations. The kit is compact and organized for easy transport and storage, and the saw cups are compatible with standard arbors and pilot bits designed for Quicklock interfaces.

Suitable for

• Cutting round openings in softwood, hardwood and plywood
• Making penetrations for plumbing pipes and fittings
• Creating cable and conduit entry holes for electrical installations
• Installing ventilation ducts and HVAC components in light construction
• Work with drill drivers and drills that accept Quicklock-style arbors

Key specifications

• Set configuration: 9-piece hole saw set with multiple diameters
• Connection type: Quicklock-style connection for rapid cup and pilot bit changes
• Material compatibility: wood, plastic, and some soft non-ferrous metals
• Cutting edge: hardened saw teeth suitable for clean cuts in recommended materials
• Intended use: manual drill and drill-driver operation for installation and maintenance tasks

How to use

Select the appropriate hole saw diameter for the required opening and attach the compatible arbor with pilot bit using the Quicklock interface. Secure the arbor into a drill or driver rated for the saw size and material. Begin drilling at low speed to establish the pilot hole, then increase speed and apply steady pressure while keeping the tool perpendicular to the workpiece. Withdraw the saw periodically to clear chips and prevent overheating. After cutting, release the saw cup via the Quicklock mechanism and remove any remaining material from the cup and pilot bit.

Usage recommendations

Use personal protective equipment such as safety glasses and hearing protection. For best results, clamp workpieces securely and use appropriate feed pressure to avoid binding. Do not use the saws on hardened steels or materials harder than specified; choose a cutting speed and cooling method suitable for the material in use.
