The table and arm of the PROXXON TBH drilling machine are made of die-cast aluminium. A refined, rust-proof and statically very solid material. Fittings and feeds are machined on CNC controlled machines (milled, line-bored, lathed, etc.). Practical height adjustment via toothed rack with easy to operate crank. The table features a ribbed base and milled work area with T-slots. The column is bright nickel-plated. Powerful, long life 230V permanent magnet motor. The quill is driven via a belt and three step pulleys. This yields a torque multiplication of as much as 6x at the lowest speed. Geared quill feed for exact operations runs in ball bearings. Spindle with 1/2"' thread accepts the industrial standard ROHM chuck.
