Drill bit KWB 598900 — diameter 3.2 cm, single-piece

Drill bit KWB 598900 — diameter 3.2 cm, single-piece is a single replacement drilling tool intended for use with right-hand rotation rotary drills. The product is supplied as one piece and is designed to create holes with a diameter of 32 mm. It is presented by the KWB brand and is compatible with standard rotary drilling tasks where a large-diameter hole is required. The tool includes a mandrel suitable for HSS bi-metal holesaws and features an HSS pilot drill to guide cutting and improve centring during use.

Advantages

The single-piece design simplifies replacement and storage while reducing the risk of losing components. A 32 mm diameter provides a clear working size for tasks that require larger holes. The included mandrel is hardened and finished with an SDS-Plus style shank for a secure connection in compatible chucks or adapters. The integrated HSS pilot drill assists in precise positioning and initial penetration, improving control when starting a hole.

Suitable for (tasks / use cases)

• Creating 32 mm diameter holes in materials compatible with bi-metal or HSS cutting edges
• Use with right-hand rotation rotary drills for general installation and fitting work
• Applications where a hardened mandrel with SDS-Plus compatibility is required

Key specifications

• Drill diameter: 32 mm
• Item quantity: single piece
• Design: single-piece drill with mandrel and pilot drill
• Mandrel type: hardened with SDS-Plus style shank
• Pilot drill: HSS pilot included
• Rotation direction: right-hand rotation

How to use

Fit the mandrel securely into a compatible rotary drill or SDS-Plus adapter according to the drill manufacturer’s instructions. Mark and centre the intended drilling point, then engage the HSS pilot drill at low speed to establish a precise start. Increase speed and apply steady, even pressure appropriate to the material being drilled, allowing the bi-metal cutting edges to remove material. Withdraw periodically to clear chips if drilling deep holes, and finish the hole at a controlled speed to maintain a clean edge.

Usage recommendations

Use appropriate personal protective equipment such as eye protection and gloves. Select drill speed and feed pressure suitable for the material; avoid excessive force that can overheat the pilot or cut edges. For masonry, concrete, or very hard materials, confirm compatibility before use. Store the single-piece drill in a dry place to prevent corrosion and keep the pilot point protected between uses.
