Bilz WF1 Straight Shank 1-1/16in

Bilz WF1 Straight Shank tapping chuck with through-coolant capability delivers coolant directly to the tap at up to 50 bar (725 psi), enabling efficient heat management and longer tool life in metalworking operations. The WF1-IKP-M variants shown in Bilz’s catalog accept DIN taps M3–M12, ANSI taps #0–9/16, and pipe taps 1/8", providing broad compatibility across common threading standards; the through-coolant design supports reliable performance in demanding environments. The WF1 family uses a compact body profile with a length of 39 mm and an outer diameter of 32 mm, and the detailed bore geometry varies by shank size—d1 and d2 are 19.05 mm and 19 mm for the 3/4" shank variant, while the 1" shank variant lists d1 as 25.4 mm with d2 remaining 19 mm. Available shank sizes include 3/4" and 1" to fit typical machine spindles. Representative model identifiers include WF1-IKP-M/3/4" with Ident No 11700623 and WF1-IKP-M/1" with Ident No 6708811, illustrating the two common configurations in this straight-shank family. This Bilz WF1 Straight Shank design centers on secure tap retention, compatibility with a wide range of taps, and efficient through-coolant delivery for precise, consistent threading results.
