A pullback system for installing product in a hole includes a rotary drill bit having a plurality of cutter elements, and a pullback device that is attachable to the rotary drill bit without disassembling the rotary drill bit or removing the rotary drill bit from a drill string. The pullback device includes a frame member and a plurality of anchor arms. Each anchor arm has a first end coupled to the frame member and a second end. Each anchor arm is configured to extend between adjacent cutter elements of the rotary drill bit. An attachment location can be used to attach product to the pullback device.

A miter saw that includes a base, a worktable arranged on the base and defining a worktable plane, and a cutting head formed with or connected to an operating member operable by a user. The cutting head further includes a circular saw blade operative to rotate around a first axis and a motor operative to drive the circular saw blade. A fence is arranged on the worktable. The cutting head is further connected to a first guiding member configured for guiding chips to be discharged. The fence is formed with a guiding portion. The cutting head is operative to rotate around a second axis parallel to the worktable plane and, when the cutting head rotates around the second axis, the guiding portion is operative to guide the first guiding member to cross the fence.

A miter saw assembly comprises a cutting tool configured to perform a cut along a cutting axis. A fence of the miter saw assembly extends longitudinally in a direction transverse to the cutting axis. A stop mechanism is linearly translatable in the longitudinal direction of the fence. A rotary motor includes a selectively rotatable rotor and a motion conversion mechanism is configured to transform rotary motion of the rotor to linear motion of the stop mechanism in the longitudinal direction of the fence. A controller is configured to selectively rotate the rotor to cause linear translation of the stop mechanism in the longitudinal direction of the fence toward or away from the cutting axis.

A compound saw, including a frame; a motor driving assembly, which is sleeved in the frame and rotatable around a first axis perpendicular to a main plane of the frame relative to the frame; and a saw blade, which is mounted on an output shaft of the motor driving assembly and rotatable around a second axis passing through the output shaft relative to the motor driving assembly. The second axis is parallel to the first axis, and there is an eccentric distance between the second axis and the first axis.

Bevel saws and methods of adjusting a fence of a bevel saw are disclosed herein. The bevel saws include a workpiece support that defines a workpiece support surface. The bevel saws also include a user-actuated assembly and an assembly attachment structure that operatively attaches the user-actuated assembly to the workpiece support. The assembly attachment structure includes a blade bevel angle adjustment mechanism configured to adjust a blade bevel angle of the bevel saw blade. The bevel saws also include a fence that defines a fence surface that extends away from the workpiece support surface. The fence includes a first fence region and a second fence region. The first fence region and the second fence region define a blade-receiving gap therebetween, and the fence further includes a gap adjustment mechanism configured to automatically adjust the blade-receiving gap based, at least in part, on the blade bevel angle.
