2 : Quick Change Tapping chuck and tapping adapter :Simply insert tap adapter into tapping chuck. :Tapping chuck and tap adapter are connected firmly. :Push down on operation sleeve of tapping chuck while removing tap adapter. :Insert tap into bottom of tap adapter, and rotate tap manually to connect them firmly. :Tap and adapter are connected firmly. :Push down on ball bush while removing tap. Safe torque device activates to prevent breakage tap when torque more than fixed amount is applied to tap. (Use with a tapper equipped with axial compensation mechanism.) Tapping adapter and Tap S : Safety torque When using left handed tap adapter, please specify. N : Length adjustment Insert hex. wrench into bottom of tap adapter and turn to adjust tool length. Tap adapter with tool adjustment mechanism can be recommended for following conditions..tool adjustment with prestting gauge..when tap length changes due to re-grinding..when you do not want to use N/C machine tool compensation function. 457

3 S B Quick Change Tap Adapter Applications For right-hand thread only. Through hole and blind hole. Feature Quick Change Safety torque clutch actuates to prevent tap breakage when an excessive torque is applied to tap. In this case, a tapping chuck with compression device should be used together. For capable tap sizes, please refer to P chart. Code Model Tap Size Chuck size D D D L L L4 L5 kg S0B SB S40B SB SB S4B M ~ M8(M0) U/4 ~ U5/6(U/8) M ~ M(M5) U/4 ~ U7/6(U9/6) Pipe(PT,PS,PF)/8 ~ /4 M6 ~ M8 U/4 ~ U/4 M8 ~ M U/8 ~ U7/8 M6 ~ M8 U ~ U /8 7/8 ~ -/4 M ~ M48.Tap sizes in brackets are for light tapping only.. Calculate tap projection length from L dimension..tapping chuck with compression device should be used together. 4.Specify PT, PS or PF when using a pipe tap, as each of them has various safety torque value. 5.L and L6 dimensions fluctuate with tap sizes. Always take into account ±.5mm allowance. 6.Refer to P.46 for tap shank dia. and square dimension Ordering Example SB M8J Adapter size Tap size 459
