A Slow-Speed Motor with a straight Handpiece Attachment is primarily designed to utilize long-shank straight bur attachments. This setup is ideal for various dental procedures that require slower rotational speeds, such as fining, polishing, or tooth preparation. Long-shank straight burs fit securely into the handpiece and allow for precision work, which is essential in dental procedures where control over speed and torque is necessary.

In contrast, high-speed attachments are not compatible as they are designed for handpieces that operate at significantly higher RPMs, intended for more aggressive cutting and drilling. Diamond bur attachments, while they can be used with slow-speed handpieces, are not specifically tied to the straight handpiece configuration, as they can also be used with other types of handpieces. Injection molding attachments serve a completely different purpose, associated with the fabrication of custom dental devices, and are not relevant to standard dental cutting or shaping techniques performed with a straight bur. Therefore, long-shank straight bur attachments are indeed the correct and most fitting choice for a Slow-Speed Motor with a straight Handpiece Attachment.
