Power drill accessory Wolfcraft 5950000 — 1 pc, compatible with power drills, accessory part

The Wolfcraft hole enlarging tool is an accessory designed to expand existing boreholes accurately and safely when using a hole saw. Supplied as a single unit, the tool features a conical plastic sleeve with integrated external thread that is screwed into the existing hole to provide firm, centred support. A steel bush in the centre accepts a centring drill bit with a 6–8 mm diameter and guides the hole saw to ensure neat, concentric enlargements. The kit includes an insertion aid that tightens the fit in the borehole so the tool remains secure during drilling. This accessory is manufactured in the European Union and is intended as a replacement or addition to a power drill kit for general drilling and fastening tasks where a compatible guiding solution is required.

Advantages

The conical design with integrated thread ensures quick, secure mounting in existing holes without complex fixtures. The central steel bushing provides reliable guidance for a centring drill bit (6–8 mm), which helps keep the hole saw perfectly aligned and prevents wandering. The insertion aid improves stability and makes the unit suitable for overhead work, reducing the risk of slipping or damage to surrounding material. The plastic sleeve and steel bushing combination is lightweight yet durable, offering consistent results when enlarging multiple holes in a series.

Suitable for

• Enlarging pre-existing boreholes to a larger diameter using a hole saw
• Upgrading recessed ceiling fittings (for example replacing halogen fittings with larger LED housings)
• Work that requires centred, repeatable hole placement such as series drilling
• Overhead drilling where a secure guide prevents slippage

How to use

Insert the conical sleeve into the existing borehole and screw it in using the integrated thread until a firm fit is achieved. Fit the centring drill bit (6–8 mm) into your drill and locate it in the steel bushing at the tool's centre to establish a precise guide point. Position the hole saw around the tool, start drilling at a steady speed and let the saw cut the enlarged diameter while the steel bushing keeps the bit centred. After completing the cut, withdraw the hole saw and then remove the hole enlarging tool together with the drilling core. Use the supplied insertion aid if additional tightening is needed to secure the sleeve during drilling.

Usage recommendations

Ensure compatibility between the hole saw arbor, centring drill bit (6–8 mm) and your drill prior to use. Wear appropriate personal protective equipment such as eye protection and gloves. Do not force the tool; allow the hole saw to cut at its recommended feed and speed. For best results when enlarging multiple holes, maintain consistent insertion depth and alignment for each hole enlarging tool placement.
