GREENFIELD THREADING 307059 Straight Flute Tap,5/8″-18,HSS 15J604
Straight Flute Tap, Thread Size 5/8 In.-18, UNF, Plug, Overall Length 3 13/16 in, High Speed Steel, TiN, Right Hand, Thread Length 1 13/16 in, 75 Percent Thread Drill Size 14.50 mm, Thread Limit H3, Class of Fit 2B The TiN coating on these taps protects them from wear and allows them to be used at higher speeds than taps with a bright finish. Non-coolant-through taps do not have coolant holes, so a separate hose is required to bring coolant to the cutting area if it is needed.

GREENFIELD THREADING 357942 Spiral Point Tap,5/8″-18,HSS 15J885
Spiral Point Tap, Thread Size 5/8 In.-18, UNF, Overall Length 3 25/32 in, High Speed Steel, Bright (Uncoated), Right Hand, Thread Length 1 1/16 in, 75 Percent Thread Drill Size 14.50 mm, Thread Limit H3, Class of Fit 2B, Number of Flutes 3 UN fine (UNF) taps have more threads per inch than UN coarse (UNC) taps. Compared to UNC taps, UNF taps perform better in threading applications on thin-walled workpieces and hard materials. Fine threads provide more tensile strength and shear strength than coarse threads. The bright finish on these taps provides a smooth, polished surface.
