The PFAFF® select™ 4.2 is a heavy-duty mechanical workhorse built for sewists who demand absolute reliability, raw puncture power, and simple manual controls — ultra-durable tactile switches in a rigid internal aluminum chassis, with an integrated needle threader and 18 complimentary accessories included (see What's Included below).
At the core of its fabric handling is the legendary Original PFAFF IDT™ System (Integrated Dual Feed), which feeds fabric evenly from the top and bottom simultaneously. From fine silk linings to thick denim topstitching and dense multi-layered quilt blocks, your fabric will never stretch, slide, or pucker out of position.

Frequently Asked Questions
What makes the PFAFF rotary hook system special? Unlike oscillating bobbin setups that vibrate back and forth, the industrial rotary hook spins continuously in one direction — quiet operation, minimal vibration, and smooth high-speed stitching without thread jams.
Can I combine stitches using the push buttons? Yes. Easy Select™ lets you depress multiple stitch buttons at once to create unique stitch patterns beyond those listed on the console.
How does it maintain piercing force at slow speeds? Electronic motor control delivers maximum, steady needle penetration force even stitch-by-stitch, so the needle doesn't stall or break on heavy seams.
