If you plan to purchase from a dealer like R S Tools & Services (or any other retailer), it’s wise to verify: That the tool is indeed the DB-R-15 model (not a variant) with the stated 3/16″ capability & 14 mm stroke. That the air compressor and hose setup you have are compatible: ¼″ air inlet, 3/8″ hose ID, and capable of supplying 50–100 psi at required air flow (6–7 CFM). Whether the riveter comes with required nosepieces to match different rivet diameters (3/32″, 1/8″, 5/32″, 3/16″) — many pneumatic riveters need nosepiece changes depending on rivet size. Whether any maintenance instructions are provided — pneumatic/hydraulic riveters need periodic lubrication/cleaning for consistent performance and longevity. The warranty/support terms (you mentioned 6-month warranty) — helpful if there are issues with seals, hydraulic parts, or wear and tear.
