![]() ![]() Reaming helps control hole size but is not required. 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. 2B Fit 6-32 H5 TICN Coat Tap – Sold in Packages of 10 $176.Jarflo roll form pipe taps (NPT & NPS) have significant advantages over cutting taps in many applications.2B Fit 5/16-18 H7 TIN Coat Standard Taps – Sold in Packages of 10 $286.00 Add to cart.2B Fit 5-40 H5 TIN Coat Standard Taps – Sold in Packages of 10 $165.00 Add to cart.2B Fit 4-40 H5 TIN Coat Standard Taps – Sold in packages of 10 $187.00 Add to cart.2B Fit 4-40 H5 TICN Coat Taps – Sold in Packages of 10 $209.00 Add to cart.2B Fit 2-56 H3 TIN Coat Standard Tap – Sold in Packages of 10 $187.00 Add to cart.2B Fit 2-56 H3 TICN Coat Taps – Sold in Packages of 10 $209.00 Add to cart.2B Fit 2-56 H3 J100 Coat Taps – Sold in Packages of 10 $330.00 Add to cart.2B Fit 12-28 H6 TIN Coat Standard Taps – Sold in Packages of 10 $209.00 Add to cart.2B Fit 12-24 H6 TIN Coat Standard Taps – Sold in Packages of 10 $209.00 Add to cart.2B Fit 12-24 H6 TICN Coat Taps – Sold in Packages of 10 $330.00 Add to cart.2B Fit 10-32 H6 TIN Coat Standard Taps – Sold in Packages of 10 $154.00 Add to cart.2B Fit 10-24 H6 TIN Coat Standard Taps – Sold in Packages of 10 $154.00 Add to cart.2B Fit 1/4-28 H6 TIN Coat Standard Taps – Sold in Packages of 10 $275.00 Add to cart.2B Fit 1/4-20 H6 TIN Coat Standard Taps – Sold in Packages of 10 $308.00 Add to cart.0 6H Fit M6 x 1 D8 TIN Coat Standard Taps – Sold in Packages of 10 $175.00 Add to cart.Provides a diamond blue/black finish that stress relieves the microstructure of the tap and provides an oxide film that reduces galling.Ĭase hardens the cutting tool surface to 66-68 Rockwell C and provides increased wear resistance with a black surface finish that acts as lubricant to reduce frictional heat and galling. It provides a hardness superior to carbide but maintains the toughness of high-speed steel. This coating is excellent for abrasive wear applications. Titanium Nitride is the standard treatment on all Stub Jarflo taps. This treatment is not recommended for tapping titanium and has performed poorly in high nickel alloys, brass and galvanized steels. The TiN treatment is ideal for the majority of forming applications. This treatment reduces the coefficient of friction and hardens the surface to 80-85 Rockwell C. Provides a layer of titanium, which is applied to the tap surface with the PVD method. All taps come with TiN coating unless otherwise noted. Metric Thread-Forming Screws for Soft Metal These metric screws have a triangular shank that presses tightly as it forms threads, so screws resist loosening in soft metals such as brass, aluminum, and. There are several different coatings offered to maximize tap life. Also known as Fastite screws, these offer more thread engagement in 0.028' to 0.063' thick sheets to prevent overtightening and damaging threads. This will give you better thread quality and alleviates the hassle of chips on your table. D/K Technologies Turret Taps are a powder metal roll form tap. ![]()
