20cm, 8″ straight Stille Chisel, 10 mm-25 mm – Surgical Bone Chisel & Gouge – 11-487-20

When a procedure calls for a broader chisel working range, Article 11-487-20 provides a straight Stille pattern measuring 20 cm, or 8 inches. The instrument is offered in working widths from 10 mm to 25 mm, giving the surgical team several options for adapting the contact area to the bone being treated. This makes it a useful member of a comprehensive bone surgery instruments set where larger bone surfaces may need controlled mechanical preparation.
The Stille configuration is well suited to situations where a surgeon wants a direct, straight approach to the bone. Compared with narrower osteotomes, the broader widths available in this pattern can provide a larger working surface when the operative task calls for more substantial bone separation or contouring.
The principal specifications are:
Selecting the correct width is important because it allows the surgeon to match the instrument to the scale of the bone surface rather than relying on one size for every application. That can make instrument selection more deliberate during orthopedic and reconstructive work.
The 20 cm length also gives the operator practical reach while retaining a familiar hand position. Article 11-487-20 is therefore a useful broader-width option for surgical trays that require several chisel dimensions. Add it to an orthopedic bone preparation set where larger working surfaces are needed.
