These items are Tapered Drill Chuck Removal Wedges (often called "Jacobs" wedges, even when made by other brands like Tuten).

Their primary function is to safely remove a drill chuck from its arbor or spindle when they are joined by a friction taper fit (like the Jacobs Tapers (JT) or DIN 238 tapers (B)).

Description and Use

Feature	Details
Purpose	To separate a drill chuck from the tapered arbor or spindle it is mounted on.
Function	They are thin, flat wedges designed to be hammered or pressed into the narrow gap between the back of the drill chuck and the shoulder (or cross-pin) of the arbor/spindle.
Mechanism	The force applied to the wedges creates an axial separating force that breaks the friction-based taper lock, causing the chuck to pop off.
Sizes	The specific designations (B16, B18, JT3, JT6) refer to the taper size of the drill chuck and arbor they are designed to work with.
Compatibility	Critical: You must use the wedge that precisely matches the taper of your drill chuck (e.g., a JT3 wedge for a JT3 taper chuck). Using the wrong size can damage the chuck or arbor.
Material	Typically made from durable steel (like Chromium Vanadium Steel) to withstand the required impact/pressure.
Set	Usually sold in a set of two pieces, which are used simultaneously and symmetrically on opposing sides for even pressure.

Taper Designations
The codes B16, B18, JT3, and JT6 refer to standard tapers used in drilling machinery:

JT (Jacobs Taper): A standardized, self-holding friction taper system.

JT3 and JT6 are two common sizes.

B (DIN 238 Taper): Another standardized metric friction taper system.

B16 and B18 are two common sizes.

The wedges are precision tools designed to fit the geometry of these specific tapers to ensure an effective and non-damaging removal process.
