I just received another screw-design related follow-up question…
My supplier is pushing a screw tip with spiral channels cut into it. These are supposed to ‘promote better output’ and ‘improve forward flow’. Is this true?
Although I have not seen any studies, I have used these myself with no problems and I know many colleagues who believe they help with screw recovery.
Although these tips intuitively make sense, I would like to see a side-by-side study comparing conventional screw tips with spiral tips to quantify the actual benefits.
