SDS Plus Adapter for 13mm Drill Chuck

A 3D-printable insert designed to fit an SDS Plus masonry bit into a standard 13mm drill chuck. This is perfect for smaller drills and situations where a full-sized rotary hammer won't fit.

• Best Use: Smaller bits up to 20–25cm long.
• Ideal for: Tight spaces (near floors/corners) where a standard hammer drill/rotary hammer is too bulky.
• Material: Highly recommended to print in ASA or PETG with 100% infill for durability.
• Important Warning: Although it can technically hold larger bits (as shown in the photos), it is not recommended for heavy-duty use. Using large bits will lead to excessive wear on your drill chuck. Use smaller bits to ensure tool longevity.
• There is no need to tighten the chuck too much just to prevent the adapter from slipping out of the groove 

ASA tested and recommended
