8 Chandler Bone Chisel 6.1 mm, Wide Bi-Bevel Tooth Splitting Chisel

The 8 Chandler Bone Chisel extends the bi-bevel splitting capability to a 6.1 mm blade width, covering the furcation and root sectioning requirements of larger-diameter teeth where the #7’s 4.7 mm blade cannot span the full width of the target split zone. The clinical situation this addresses is the maxillary first molar specifically: the trunk of the maxillary first molar is wide in the buccopalatal dimension and the separation between the mesiobuccal, distobuccal, and palatal roots at the furcation level is broader than in mandibular molars. A 4.7 mm chisel positioned at the furcation of a maxillary molar may not span the full width of the target sectioning plane, leaving the instrument seated asymmetrically and increasing the risk of an angled rather than a straight split.

The 6.1 mm blade of the #8 covers this wider furcation diameter, providing stable seating across the full sectioning plane before the mallet stroke drives the blade. The bi-bevel symmetric force distribution then separates the tooth halves with equal lateral force to both sides, which is the controlled splitting action that protects adjacent alveolar bone from crack propagation in an unintended direction. Mallet-compatible round platform handle, medical-grade stainless steel, autoclavable.

Product Features

• Chandler bone chisel 8 wider 6.1 mm bi-bevel blade stabilizes across broader furcation diameters where the 4.7 mm #7 would seat asymmetrically
• Suited to maxillary molar furcation sectioning and large-diameter root separation
• Bi-bevel symmetric force distribution produces controlled bilateral tooth split
• Mallet-compatible handle; medical-grade stainless steel, fully autoclavable

#8 vs #7: The wider bi-bevel at 6.1 mm. Select the #8 when the tooth being sectioned has a wider furcation diameter or heavier root bulk than the #7’s 4.7 mm blade can stabilize effectively at the split point before mallet force is applied.
