Tools and Hardware Reviews of DELTA DP350 Shopmaster 1/3HP 12-Inch Bench Drill Press

Customer Review: Good variable speed drill press, great price
Summary: 5 Stars

Head assembly - The motor, spindle and speed control system are solidly fixed to a one-piece cast iron frame. Sheet steel panels complete the remainder of the enclosure. Rubber pieces isolate the top cover. The depth control system has a quick adjust feature. All of these work well.

Constant speed drive system - This is probably the costliest part of the machine for Delta to produce. The variable speed drive system is quite simple, but requires some solid, precision components - and they seem quite well made in this machine. The speed control operated smoothly, and the noise and vibration levels from the drive system were very reasonable. I might try a link belt for fun to see if it's any smoother, but it works pretty good as is. ... I'm real happy getting this good of a variable drive system.

Runout - Without a dial indicator, and the Jacobs chuck installed, I looked for signs of runout. I mounted a short router bit and a longer bullet point bit. With my bare eyeball, I couldn't see any runout. At high speed the long bit ran very smooth - no wobble. At least no signs of excessive runout.

Perpendicularity of the spindle to the table - I checked this with a good straight bit mounted in the chuck, and rotated it to different quadrants. Using my best machinist square, fore and aft squareness was right on. This is most important because it is not adjustable and accounts for the total accuracy of the head, column and table. Side to side squareness is controlled by table tilt, which is adjustable. I was able to adjust this perfect as well, with a little work.

Table - The table has drip channels for metal cutting. With straight edge, the table looked to be within .001-.002 inches flat. The milling was slightly rough but ok.

The table can be tilted, but the angle-of-tilt indicator is pretty useless - the weakest feature of this product. There is a pin to locate the table at 90 degrees, but it isn't real convenient to use. I will probably avoid tilting the table and get a good tilting vise.

The table height adjusting system worked fine.

Base and column assembled and worked fine.

Packing good, but the box was open - luckily nothing missing. Rust preventative on everything. Small suggestion to Delta: the spindle needs more clearance to the box in case the box is dented in.
