It delivers a \u003cstrong\u003e1\/32\" stroke\u003c\/strong\u003e with adjustable impact force — from light to heavy — controlled by rotating the silver knurled adjusting ring.\u003c\/p\u003e\n\n\u003cp\u003eUnlike rotary handpieces, the H.15 operates with a reciprocating motion, making it ideal for \u003cstrong\u003estone setting\u003c\/strong\u003e as its primary application. It can also be used for texturing work, most effectively with the pavé point (diamond tip) accessory (Otto Frei part number 153.195), which produces a bright-cut stippled effect. The H.15 is also compatible with the Foredom Carbide Tip (HP10212, Otto Frei part number 134.301) for marking or inscribing hardened steel.\u003c\/p\u003e\n\n\u003cp\u003eThe H.15 is supplied with a hardened tip. Tip threads are \u003cstrong\u003e4-48 US thread\u003c\/strong\u003e, the same standard used on popular Badeco tips — meaning tips are interchangeable between the H.15 and the Swiss-made Badeco hammer handpiece.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eImportant:\u003c\/strong\u003e Use at low speed only (0–5,000 rpm) and only in forward rotation.
