Depth stop assembly for a portable electric drill

A depth stop assembly mountable to a housing of a portable electric drill including a housing having a threaded aperture and an adjacent recess, an electric motor, and a chuck operatively driven by the electric motor about a drill axis, the depth stop assembly comprising:

• a depth stop rod;
• a fastener having an engagement end which is releasably securable within the threaded aperture in the housing;
• and
• a mounting block having a mounting surface cooperating with the housing, a projection extending from the mounting surface and projecting into the recess of the housing, a first aperture spaced from the housing and extending about a first axis generally parallel with the drill axis through which the depth stop rod is movably mounted, and a second aperture extending about a second axis along which the fastener extends, wherein the mounting block has a first mounting block half and a second mounting block half, the mounting block halves cooperating to releasably capture the depth stop rod therebetween;
• wherein when the fastener is secured within the threaded aperture in the housing, the fastener and mounting block cooperate to prevent the depth stop rod from moving axially along the first axis.

A portable electric drill assembly comprising:

• a drill including a housing having a threaded aperture and at least one recess adjacent to the threaded aperture, an electric motor, and a chuck operatively driven by the electric motor about a drill axis;
• a depth stop rod;
• a mounting block having a mounting surface adapted to cooperate with the housing, a first aperture spaced from the housing for supporting the depth stop rod generally parallel to the drill axis, and a second aperture extending along a fastener axis, the mounting surface having a projection thereon which is cooperatively received by the at least one recess in the housing;
• the mounting block including a first mounting block half having the mounting surface thereon and a second mounting block half which cooperates with the first mounting block half to releasably capture the depth stop rod therebetween while preventing relative rotation of the first and second mounting block halves above the fastener axis;
• a rotatable handle;
• and
• a fastener extending through the mounting block second aperture along the fastener axis and having two ends respectively cooperative with the housing threaded aperture and the handle to releasably entrap the mounting block therebetween to enable a user to adjustably position the depth stop rod relative to the housing.
