## Long description

DeWalt DT1939-QZ is a circular saw accessory with an inner diameter of 16 mm, outer diameter of 184 mm and a thickness of 1.2 mm. It is intended as a replacement mounting washer/spacer for compatible circular saw blades and blade carriers, providing the precise concentric fit required for stable rotation and reliable cutting performance. The accessory matches the dimensional requirements of many stationary circular saw setups used for cutting natural wood and composite materials.
Advantages
The accessory’s exact inner and outer diameters ensure a secure fit on shafts and blade carriers, reducing runout and vibration during operation. Its 1.2 mm thickness offers a balance between rigidity and ease of mounting, contributing to consistent blade alignment. Constructed for use with heavy-duty saw blades, the design supports nail-resistant performance and durability when used in demanding cutting tasks on timber and formwork materials.
Suitable for
Replacement mounting spacer/washers for stationary circular saws
Cutting applications on natural wood and composite formwork materials
Workshops and industrial settings requiring robust blade mounting
Key specifications
Inner diameter: 16 mm
Outer diameter: 184 mm
Thickness: 1.2 mm
Compatibility: designed for use with circular saw blades and carriers that accept 16 mm bore and 184 mm outer seating
Application: suitable for stationary circular saws handling timber and composite materials
How to use
Fit the accessory onto the saw arbor so the 16 mm inner diameter seats securely on the shaft and the outer diameter aligns with the blade mounting surface. Ensure the blade and spacer are clean and free from debris before tightening the flange nut or retaining mechanism. Tighten according to the saw manufacturer’s torque recommendations to avoid distortion; then verify runout and blade alignment before making cuts. Replace the accessory if any deformation or excessive wear is observed.
Usage recommendations
Use this accessory with blades specified for stationary circular saws and follow all safety instructions from the saw and blade manufacturers. Inspect mounting faces regularly and confirm that the spacer’s dimensions match the blade and arbor system to maintain cutting accuracy and operator safety.
