YATO Spot Weld Drill Bit Set YT-28921, 3-piece spot weld drill bits

The YATO Spot Weld Drill Bit Set YT-28921 is a three-piece collection of drill bits engineered for cutting and removing spot welds from sheet metal. Designed for use with hand-held drills and drill presses, this set supports controlled separation of joined panels and access to welded seams in automotive bodywork and metal fabrication. The bits are intended to simplify the process of removing spot welds while minimising damage to surrounding material when used with appropriate technique and equipment.

Advantages

This three-piece set delivers a range of sizes to match common spot weld diameters, reducing the need to change tools frequently. The bits are made for reliable cutting performance on sheet metal and are compatible with standard drill chucks, enabling use in both portable drills and drill presses. Their design focuses on precise removal of weld material, which helps preserve panel integrity and speeds up repair and fabrication workflows.

Suitable for

• Automotive body repair and panel replacement
• Sheet metal fabrication and modification
• Removing spot welds to access seams and joints
• Maintenance and restoration work on metal assemblies

Key specifications

• Set composition: three spot weld drill bits in progressively different diameters
• Intended materials: sheet metal and thin-gauge steel panels
• Compatible tools: hand-held drills and drill presses with standard chucks
• Application focus: cutting and removing spot welds for panel separation

How to use

Select the drill bit size that matches the spot weld diameter and secure it in the drill chuck. Position the drill perpendicular to the weld and run the drill at an appropriate speed for thin metal, using steady pressure to cut through the weld without pushing through the base material. Work progressively and stop frequently to inspect the cut; once the weld material has been removed, separate the panels carefully and finish the edge as required. Wear appropriate personal protective equipment and follow the drill and workshop safety guidelines while operating.

Usage recommendations

Use moderate drill speed and firm, controlled pressure to reduce heat buildup and avoid damaging surrounding metal. If access or visibility is limited, consider a backing support behind the panel to prevent deformation. After separation, remove burrs and clean mating surfaces before further bodywork or welding.
