【 Four Blade Reamer 】 This pipe reamer features four high hardness stainless steel blades to process both inner walls and outer edges of 1/4 to 1 5/8 inch(6-42mm) pipes . It works on copper and plastic pipes like PVC and CPVC to create smooth flat ends , improving joint assembly quality 【 Easy to Use 】 For deburring : Align the pipe end with the blade , rotate clockwise or counterclockwise a few times to finish inner/outer chamfering and deburring . For the depth gauge : Simply slide it over the pipe end , push to the stop position , and mark the insertion line with a marker , greatly reducing installation errors and boosting first time success rates 【 Wide Compatibility for Various Pipe Types 】 This pipe reamer and depth gauge set fully supports mainstream pipes like copper , PEX , CPVC , PE-RT , and SDR-9 HDPE 【 6 in 1 Depth Gauge 】 The depth gauge integrates 6 common sizes : 1/4" , 3/8" , 1/2" , 5/8" , 3/4" , 1" . The C shaped limit blocks for 1/2" and 3/4" can detach or adjust push by hand (no extra tools needed) , allowing quick adaptation to different pipe fitting needs , suitable for crimping , gluing , or mechanical connections 【 What You'll Receive 】 You'll get a pipe deburring tool and a depth gauge . The pipe deburring tool effectively cleans burrs from cut copper , PEX , and PVC pipes , while the depth gauge precisely marks insertion depths, Manufacturer: PATNFR
