Kurt SKOA10.11 | 5/8 x 11/16" Vise Sine Key - Pair

Description

The Kurt SKOA10.11 Vise Sine Key pair is a precision alignment accessory made to give repeatable, measurable setup for Kurt vises and sine plate fixtures. Each set contains two non-expandable O-ring-style keys in English sizing that are designed to seat securely in mating slots and maintain positional accuracy during machining operations. To ensure a consistent fit, dimensions are controlled to the specification (B = 0.6245", C = 0.687", A (Theta) = 0.625"); nominal sizes for step seating are 5/8 vs 11/16. These sine keys, designed for hardened durability and corrosion resistance, are ideal as a Kurt Vise Sine Key Pair or as a vise alignment tool for DX4/DX6-style fixtures. The SKOA10.11 set is technically focused and measurement-driven, allowing for precise, repeatable setups and reducing the amount of time spent manually aligning before cutting operations.

Product Features and Benefits

Precision 5/8 x 11/16 stepped profile

Controlled dimensions (B = 0.6245", C = 0.687", A = 0.625") deliver accurate engagement for sine seating and remove ambiguity between 5/8 and 11/16 fits. The stepped profile ensures reliable mechanical registration in standard Kurt slots.

Non-expandable O-ring-style construction

The Kurt SKOA10.11 Vise Sine Key features two-piece non-expandable O-ring-style keys that resist deformation under clamping loads and maintain alignment over repeated cycles, improving long-term positional repeatability.

Durable material and finish

Heat-treated steel construction with machinable finishes provides wear resistance and long service life in shop environments typical of production and toolroom use.

Compatibility with Kurt DX4/DX6 and common sine fixtures

Specifically suited as a sine key for Kurt DX4/DX6 vise systems and compatible sine plates, making it a straightforward vise alignment tool for retrofit or replacement applications.

2 pieces of a Non-expandable O-Ring Style (English).
