This Royal SQF type quill punch/perforator punch/core pin blank has a cylindrical head and a straight shank. It is made from your choice of either M2 high-speed steel heat-treated to 60-63 Rc, or O1 oil-hardening steel heat-treated to 58-60 Rc. We draw the heads back to a lower hardness on the O1 pins when the shank is greater than 1/16 (.0625) inches. Regardless of the steel type you choose, your pins will be precision form-ground for better tolerance and finish. We grind the shank to your required shank diameter within a tolerance of +.0003/-.0000.The available fractional inch diameters are 1/16, 3/32, 1/8, 5/32, 3/16, 7/32, 1/4, 5/16, and 3/8. Please contact us if you need a diameter manufactured to a different fraction, or if you need us to make any alterations.RELATED: Royal SQD Pins in Decimal Inch DiametersDELIVERY TIME: Normally in stock and ships the next business daySHIPS FROM: Royal Pins products are sent directly to you from the factory in Warren, RIMINIMUM ORDER: Your order receives immediate processing when it includes at least $35 in Royal Pins products.
