Centering drill bit, Wolfcraft 5955000 — 1 pc, right-hand rotation, for drill and rotary hammer

The Wolfcraft centering drill bit 5955000 is a single-piece centring tool designed for use with drills and rotary hammers equipped with an SDS Plus chuck. It features a ground centring drill of 8 mm diameter and 80 mm length that enables precise positioning of starter holes before the main drilling operation. The tool is intended for rotating use (not hammering) and includes an M16 threaded connection to make the SDS Plus mandrel compatible with Wolfcraft diamond-tipped annular bits.

Advantages

This centering drill bit provides accurate hole positioning and reliable guidance for larger drill or annular bits, reducing drift and improving final hole quality. The 8 mm ground centring tip and 80 mm length offer a stable starting point in concrete, brick and stone, while the M16 threaded connection ensures compatibility with compatible diamond annular bits. The right-hand rotation design matches standard drill operation and the single-piece construction minimizes play for consistent centring.

Suitable for

• Starting pilot holes in concrete before using larger drill bits or core cutters
• Positioning holes in brick walls and stone where precise alignment is required
• Use with SDS Plus chucks and compatible Wolfcraft annular bits (rotational use only)
• Guiding diamond-tipped annular cutters via the M16 connection

How to use

Insert the centring drill bit into an SDS Plus mandrel or chuck that accepts M16-connected annular cutters, ensuring secure engagement. Fit the mandrel into an SDS Plus drill or rotary drill and set the tool to rotation mode only; do not use hammering action. Position the centring tip at the desired drill location, start the drill at low speed to establish the starter hole, then increase speed as required. Once the starter hole is established, proceed with the larger drill or annular cutter by threading it onto the M16 connection or sliding it over the mandrel as appropriate.

Usage recommendations

Use the centring drill exclusively in rotation mode with SDS Plus-compatible drills; avoid hammer drilling to prevent damage to the centring tip and mandrel. For best results when drilling concrete, brick or stone, start at low speed to avoid wandering, maintain firm and steady pressure, and use compatible Wolfcraft diamond-tipped annular bits when enlarging the hole. Inspect the centring tip before use and replace it if excessively worn to preserve hole accuracy.
