A tool bit includes a drive portion configured to be engaged by a tool, a shank extending from the drive portion, and a tip coupled to an end of the shank opposite from the drive portion. The tip has a compressive residual stress layer formed by laser ablating the tip with a laser beam to increase a wear resistance of the tip relative to the shank.

Tool bit

An accessory tool includes an adapter end, and a shank coupled to the adapter end and including a first length. The shank includes a tool engagement portion, and a first reduced portion disposed between the tool engagement portion and the adapter end. The first reduced portion has a second length. The shank additionally includes a second reduced portion formed in the tool engagement portion between the first reduced portion and an end of the shank. The second length is 2.5% to 15% of a total length of the accessory tool.

Accessory tool

A tool case including a base having a lower surface and a tool holder insert supported by the base. The lower surface of the base defines a plurality of guides. The tool holder insert includes a base portion, an insert portion extending from the base portion in a first direction, a main body portion extending from the base portion in a second direction that is opposite the first direction, and a wing extending outwardly from the base portion. The insert portion engages one of the plurality of guides. The main body portion is configured to receive an oscillating multi tool blade, and the wing has a detent that engages another of the plurality of guides.

Drive guide

A tool bit for driving a fastener includes a shank including a tool coupling portion configured to be coupled to a tool, a head portion configured to engage the fastener, and a nickel coating on the head portion. The head portion is composed of powdered metal (PM) steel having carbide particles distributed uniformly throughout the head portion.

Wear resistant tool bit

A tool bit includes a drive portion configured to be engaged by a tool, the drive portion including a first maximum outer dimension, a shank extending from the drive portion and including a reduced outer diameter, and a tip coupled to an end of the shank opposite from the drive portion. The tip includes a compressive residual stress layer formed by blasting to increase a wear resistance of the tip relative to the shank. The tip additionally includes a second maximum outer dimension. The reduced outer diameter of the shank is smaller than the first maximum outer dimension of the drive portion and the second maximum outer dimension of the tip.

An auger includes a body having a first end, a second end opposite the first end, a stem that extends from the first end to the second end and defines an axis of rotation, and a flute helically wrapped around the stem. The auger also includes a shank at the first end of the body configured to be received by a power tool and a cutting head at the second end of the body. The cutting head includes a cutting edge, a spur, a feed screw with a thread, and a cutting face positioned adjacent the cutting edge. The cutting head defines a step at an interface with the body, and wherein the cutting head has a maximum diameter that is greater than a maximum diameter of the body.

Drill bit

A magnetism booster assembly includes a body having a first end and a second end. The body defines a bore and a cavity formed separately from the bore. The bore extends between the first end and the second end. The cavity has a first opening adjacent the first end of the body and a second opening adjacent the second end of the body. The magnetism booster assembly also includes a magnet positioned within the cavity.

Tool

A lockable adapter is configured to couple a drive socket to a tool. The lockable adapter includes a body defining a longitudinal axis. The body is configured to couple the lockable adapter to the tool. The lockable adapter includes a sleeve moveably coupled relative to the body along the longitudinal axis of the body between a first position and a second position. The sleeve is configured to interface with the drive socket to support the drive socket on the sleeve. The lockable adapter includes a collar moveable relative to the sleeve. The sleeve moves into the second position configured to lock the drive socket to the sleeve in response to inserting the drive socket onto the sleeve. The sleeve moves into the first position configured to allow removal of the drive socket from the sleeve in response to moving the collar relative to the sleeve.

Lockable drive socket adapter

An angled adapter for coupling a tool bit to a tool includes a housing and a transmission assembly positioned in the housing. The transmission assembly is configured to convert an input torque about a first axis from the tool to an output torque about a second axis acting on the tool bit. The second axis is disposed at an angle relative to the first axis. The angled adapter also includes a shank supported by the housing and including a tool coupling portion configured to couple to the tool. The tool coupling portion has an outer dimension. The shank also includes a transmission coupling portion coupled to the transmission assembly, and an intermediate portion extending between the tool coupling portion and the transmission coupling portion. The intermediate portion has a diameter that is less than the outer dimension.

Angled adapter

A drive guide connectable to a power tool includes a shank, a barrel, and a sleeve. The shank includes a tool coupling portion and a barrel coupling portion. The barrel is coupled to the barrel coupling portion of the shank. The barrel includes a bit coupling portion configured to couple to a tool bit. The barrel also includes a first depth indicium disposed on a surface of the barrel and a second depth indicium disposed on the surface of the barrel. The second depth indicium is circumferentially spaced about the barrel from the first depth indicium. The sleeve is disposed concentrically about and slidable along the barrel. An edge of the sleeve provides a visual indicator to determine depth based on the first and second depth indicia.

A tool bit for driving a fastener includes a shank having a tool coupling portion configured to be coupled to a tool. The tool coupling portion has a hexagonal cross-sectional shape. The shank also has a head portion configured to engage the fastener. The head portion is composed of powdered metal (PM) steel having carbide particles distributed uniformly throughout the head portion.
