9/10/2023 0 Comments Forming tap drill hole size cold![]() When drilling holes, its important to choose the right drill bit and apply enough pressure to ensure. Reaming helps control hole size but is not required. The recommended tap drill size is 0.2570 or 0.2610 inches. Straight pipe threads can be form tapped using only a high quality drilled hole.Straight hole procedure will reduce tapping torque and improve tool life. The benefits of burnished, high quality threads at the top of the hole provide excellent sealing capability for the part. The bottom of the hole may have partially formed crests with open “RABBIT EARS”. The straight hole method will result in a full, sharp-crested threads at the top of the hole. The Jarflo tap will ultimately produce the proper tapered thread by forming the material from the top to the bottom of the hole. Straight Hole – many applications for tapered pipe threads may use a straight hole.Tapered holes require the most torque and HP for tapping. Tapered hole may be drilled, reamed or cored. Tapered Hole – A pre-tapped tapered hole will result in a consistent percent of thread height the entire depth of thread in the piece part.There are two choices in the hole preparation for a Jarflo tapered pipe tap: It is not practical to thread form NPTF & NPSF threads because 100% thread is required, and the crests need to be fully formed. These benefits include improved thread finish, stronger threads, longer tap life, faster tapping speeds and no chips. See Supplemental Topics for Anchors or visit for more corrosion information.Jarflo roll form pipe taps (NPT & NPS) have significant advantages over cutting taps in many applications. Not for use in other corrosive or outdoor environments. Intended for some pressure-treated wood sill plate applications. Mechanical galvanizing meets ASTM B695, Class 65, Type 1. Titen HD® Anchor Product Data - Mechanically Galvanized ![]() using a torque wrench, driver drill or cordless 1/4" impact driver with a maximum permitted torque rating of 100 ft. Drill Size Basic Major Diameter - 0.375P. ![]() * These models do not meet minimum embedment depth requirements for strength design and require maximum installation torque of 25 ft. To insure a properly tapped (cold formed) hole, adhere to the following: For 60 Metric Threads: Max. Titen HD® Anchor Product Data - Zinc Plated Length of anchor is measured from underside of head to end of anchor. Models THD37134H and THD37212H do not meet minimum embedment depth requirements for strength design and require maximum installation torque of 25 ft. Larger holes are not required for wood or thinner cold-formed steel members. Suggested fixture hole sizes are for structural steel thicker than 12 gauge only. ![]()
