title: "Northtech NT 660S-20HCVS 20 HP Single Surface Planer (w/ Helical Cutterhead Head)"
description: "This Northtech NT-660S series single-surface planer opens wide to accept material up to 12\" (H) by 26\" (W). A soft-start 20 HP motor drives the 4\" helical cutter head with six (6) rows of two-sided inserts. The cutter head is dynamically balanced to ensure a quieter operation and smoother cuts. A 2 HP motor provides steady feed rates from 5 to 75 FPM, precisely controlled through a variable frequency drive. Digital displays for both the feed-rate and cutter height allow quick set-up and accurate adjustment. "

# Northtech NT 660S-20HCVS 20 HP Single Surface Planer (w/ Helical Cutterhead Head)

#### Cutter Heads:

-  Cutterhead Motor:  20HP, 3PH 230/460 Volt

#### Features:

- The Helical 4″ cutterhead provides a high chip removal rate, superior surface finish & low noise level (under 85 dba).

- A powerful 20 HP cutterhead motor and 2 HP feed motor makes this planer ideal for heavy-duty planing and meets high production requirements. Arranged with Y-Delta soft start controls (Square D).

- Digital positioning controller for convenient thickness setting (with memory control to 99 thickness settings).

- Variable feed speed is driven by a VFD and TECO inverter duty DC motor (0-90′ min) with an LED readout of feeding speed.

- Powered table elevation for fast and convenient thickness setting. The opening has been increased to 12″ on  NT-660S series planers vs. 8″ on the standard NT-660 planers.  

- Extra heavy, rib-reinforced cast iron table is surface precision ground. 660S-20HCVS has (4) precision 35mm jackscrews to support the planer’s rugged construction.

- Adjustable bed rollers ensure fast and proper positioning with regard to rough lumber to finished glue panels.

- UV rubber outfeed roller provides an optimum finish with reduced vibration.

- Corrugated sectional infeed roller has an independent yield for running strip stock of varying thicknesses without the danger of kickback.

- Anti-kickback fingers equipped at the infeed end provide added safety for the operator.

- Raising and lowering limit controls for powered table elevation
