Compression Testers -- Professional Guide
A drill press holds a drill bit precisely perpendicular (or at a set angle) to the work surface, producing accurate holes that hand drilling cannot achieve. The quill feeds the bit into the material at controlled depth; the table raises, lowers, and tilts for different setups. Bench-top models handle most shop work; floor-standing models provide more capacity and power.

Buying Guide: What to Know Before You Buy
How Compression Testers Are Used
Preferred for any hole-making that requires precision location, consistent depth, or perpendicularity. Woodworkers use drill presses for mortising, doweling, and boring operations. Machinists use them for initial hole drilling before reaming. Metal fabricators use drill presses to drill accurate holes in fixtures and parts.
Leading Brands
Jet, Powermatic, and Rikon make professional floor-standing drill presses preferred by serious woodworkers and machinists. WEN and Delta offer solid benchtop options. Clausing and South Bend produce industrial-grade machines found in machine shops.
What to Inspect
Check runout in the chuck with a test bar or bit -- the bit tip should not wobble at operating speed. Verify the quill moves smoothly and the depth stop works accurately. Check the table for cracks and verify the tilt mechanism locks solidly. Listen for bearing noise at operating speed.
