Irwin 8-32 NC Taper Bottom Bulk HCS Machine Screw Tap (1224ZR)

Irwin 8-32 NC Taper Bottom Bulk HCS Machine Screw Tap (1224ZR) is a precision threading tool crafted for creating standard 8-32 NC threads. This tap is an essential component for any toolbox, suitable for professionals and DIY enthusiasts engaged in a variety of repair and fabrication tasks. Made from high carbon steel, it provides a solid balance of hardness and toughness, making it effective for hand-threading work in a wide range of materials. Its design focuses on practicality and efficiency, with a bottoming chamfer that allows it to create threads all the way to the base of a blind hole, a task where other tap types fall short. The four straight flutes are a key feature, engineered to provide rapid chip removal and prevent material buildup, which is critical for producing clean and accurate threads.KEY FEATURES AND BENEFITS: Creates Standard 8-32 NC Threads: Designed specifically for a common machine screw size, ensuring compatibility with many fasteners and applications. High Carbon Steel Construction: Provides hardness and toughness ideal for manual threading use. Bottoming Chamfer for Blind Holes: Short tapered lead (1-2 threads) enables threading to the bottom of blind holes. Efficient Chip Removal: Four straight flutes quickly and cleanly remove chips, preventing clogging and ensuring smooth threading. Class 2B Thread Fit: Produces a standard general-purpose fit suitable for most applications.SPECIFICATIONS: Manufacturer’s Part #: 1224ZR Thread Size: #8-32 NC Number of Flutes: 4 Material: High Carbon Steel Thread Direction: Right Hand Tap Chamfer: Bottoming Measurement Type: Inch Surface Finish: Bright/UncoatedHOW TO USE: Preparation: Ensure hole is correctly sized using a #29 drill bit for 8-32 NC threads; clean out any debris. Lubrication: Apply cutting fluid or tapping lubricant to reduce friction and improve thread quality. Starting the Tap: Place tap straight into hole and use a tap wrench to apply even downward pressure while turning clockwise. Cutting the Threads: Turn clockwise a half to full turn, then back off a quarter turn to break chips and prevent binding. Finishing the Thread: Continue the forward-and-reverse motion, periodically removing the tap to clear chips, until desired depth is reached.BENEFITS OF USING IRWIN 8-32 NC TAPER BOTTOM BULK HCS MACHINE SCREW TAP (1224ZR): Reliable performance meeting Irwin Hansons quality standards.
