18M – Medium Multi-use Heavy Duty Pen

Versatile: Make your own tips from almost any heating wire! Accepts almost any thickness of tip wire from 16-22 ga. as well as most Razertip® tips. You can even mount two tips in the head at the same time for double-line burning (HD cord recommended; higher heat setting required). Dependable: Stainless-steel binding-post screws hold your tip wire securely against a double-slotted stainless-steel nut that is easily tightened with a small slot screwdriver. The screw can be removed to facilitate cleaning when necessary. Comfortable: The binding-post screws and nuts on this pen act as an effective heatsink, slowing the transfer of heat from the tip into the pen body. The BPH is one of the coolest operating pens made today. The best tips for use in the BPH Pen are those tips identified as "TH" Tips as they are a heavy-duty style.

The larger set includes all 10 tips; the 5 from the # SET99X5 plus 0.4mm(1/64"); 0.8mm(1/32"); 1.2mm(3/64"); 1.5mm(1/16"); 2.0mm(5/64"); 2.3mm(3/32"); 3.0mm(1/8"); 3.9mm(5/32"); 4.7mm(3/16"); and 5.5mm(7/32") tips. Use with # BPH interchangeable-tip pen.
