Svasatore KWB modello 120940 – utensile per svasare, 1 pz.

KWB countersink model 120940 is a single-piece countersink tool designed to create chamfers and deburr holes in a range of materials. Supplied as one piece, the tool prepares holes for fasteners and produces clean edges for improved screw seating. It is suitable for use in hand-held drills and machine-driven spindle applications where the shank size and drill speed are compatible with the material being worked.

Advantages

The countersink offers precise chamfering and consistent deburring in a compact, single-piece design that reduces vibration and enhances control. Its geometry provides uniform countersink diameter and smooth edge finish, helping to prevent fastener misalignment. Durable manufacturing and straightforward mounting make it a practical choice for tradespeople and DIY users requiring repeatable results.

How to use

Secure the countersink into the drill chuck ensuring correct alignment and tight clamping. Select an appropriate drilling speed for the material and apply steady, moderate pressure while advancing the tool into the pre-drilled hole to form the chamfer. Withdraw periodically to clear swarf and inspect the chamfer until the desired seat is achieved. For machine use, confirm spindle compatibility and recommended speeds for the material type.

Recommendations

Use cutting fluid or light lubrication when working with metals to improve finish and tool life. Match drill speed and feed to the material: lower speeds for hard metals, higher speeds for softer materials such as wood and plastics. Inspect the chamfer diameter regularly and replace the tool if wear affects finish quality.
