RIKON’s #70-800 Woodturning System includes a 16” long, machined aluminum
Handle with an anti-vibration grip and features a keyless chucking system for
attaching the hafts with cutters to the handle. Simply unscrew the knurled
chuck collet to insert any of the three supplied shafts with carbide cutters,
tighten the chuck collar, and you are ready to turn! No tools are required!
Three, 8-3/8” steel Shafts (70-805) are supplied along with Round, Square and
Diamond shaped tungsten carbide Insert Cutters that are secured to the shafts’
working end with a T20 screw.
USAGE NOTE: The finely machined shafts have bottoms that are milled with flat,
and 2 side bevels for extra stability on the tool rest when turning. The
bottom flat is in line with the cutter to maintain the cutter in a flat
position for scrape cutting. The two-side bevel surfaces also give the user
extra support when the cutter is shifted to an angled new position for shear
cutting action. Flats give the support and control needed, especially when
turning bowl interiors where the cutter is extended out far from the tool
rest.
TUNGSTEN CARBIDE INSERT CUTTERS
These long-lasting, extremely hard cutters work through the hardest woods in
either a scraping or shear cutting mode. Made of premium micro grain carbide,
these inserts can be sharpened with diamond abrasives. Simply lap the entire
TOP surface only to reveal a new cutting edge. Do not sharpen or change the
angle of the bevel edge.
Some cutters may include a dot • on the top surface. This dot is simply a
reference point to help users when rotating a cutter to a new set if the
working edge becomes dull.
NOTE: Carbide inserts cutters are primarily used for the final shaping
and detailing of turnings. The variety of cutter shapes will provide you with
many options for shaping and decorating your turnings. When used for roughing
out blanks, this should be done with careful, slow cuts to avoid loosening the
mounting screw or damaging the cutter from the heavy impacts that are
encountered. The R2 Square Cutter 70-814 is the best shape for this work.
3 Insert Cutters included with the Set:
ROUND Insert Cutter – # 70-810
Very effective for finishing cuts on bowl interiors or any cove or contoured
designs on bowls and spindles.
SQUARE Insert Cutter – # 70-811
Straight edges on this carbide cutter make it extremely useful for shaping
convex or straight surfaces. Ideal for producing tenons for furniture
construction. Reposition and use a corner for 90° V-cuts.
DIAMOND Insert Cutter – # 70-812
Mainly used to add thin line details on turnings, the spear-point tip is great
for undercutting and creating small beads. The long sides of the cutter are
also useful for fine shaping f rims on bowls or plates. Use carefully, as
excessive pressure on the tip from hitting knots, irregular wood grain, or
aggressive use could damage the cutter.
**Additional Insert Cutters
**
NEGATIVE RAKE Insert Cutters
Developed primarily for use in pen turning using plastics, acrylics, resins,
and dense woods, these carbide cutters feature an additional top bevel grind
*. This lower bevel angle reduces the inserts’ cutting action for the final
shaping of these hard materials. Available in 5 profiles: Circle 70-810NR,
Square 70-811NR, Diamond 70-812NR, Detail Diamond 70- 19NR, and R2 Square
70-814NR. See Page 4 for additional Carbide Insert Cutter shapes.
ASSEMBLY
Install the Carbide Insert Cutters onto the working ends of the shafts with
the supplied mounting screws and T20 star wrench. The cutter’s relief bevel
should be facing down. not over-tighten the screws or damage to the cutters
or screw threads may result.
Some specialty cutters (Ex: 70-816 Fingernail or 70-817 Paisley Left) are designed to be mounted in various positions for turning interior relief or undercuts on bowls and platters (see below). If cutters are set on an angle to the axis of the shaft, the use of the Side Handle 70-804 (sold separately) is recommended to better control the cutter from dipping during work.
Install the Shaft into the turning handle.
The front of the handle features an internal compression chuck that securely
attaches the shaft to the handle.
- Grasp the two knurled sections of the handle’s front section and turn the forward chuck counterclockwise to loosen the chuck.
- Insert the rear, 14mm diameter end of the shaft into the handle. The shaft has an alignment screw that needs to be positioned into one of the slots milled into the forward nose of the handle.
- With the shaft fully inserted into the handle, turn the knurled forward chuck clockwise to secure the shaft in the handle.
MAINTENANCE
- Keep cutters sharp. If an edge becomes dull, simply lap the entire TOP surface only on a diamond stone to reveal a new cutting edge. Do not sharpen or change the angle of the bevel edge.
- Keep the threads clean on the mounting screws and tap screw holes in the shafts. Remove any dust, resin, or moisture buildup to ensure the mounting of the cutters is secure. Lightly grease or oil the screws and shafts to prevent rusting.
- Clean all parts of the woodturning system after every use to avoid future problems and ensure the tools are ready for the next time they are used.
- Do not use and replace any damaged parts to avoid possible injury while turning. RIKON will not issue replacements or refunds if products are damaged from improper use.

Optional Accessories for use with the #70-800 Woodturning System
The 16” handle supplied in the set is hollow with a removable end cap. If a
longer handle is desired for extra leverage when the cutter is extended out
from the tool rest (typical use when turning bowl interiors), a separate 6”
Handle Extension is available. This short handle section screws into the rear
of the 16” handle, then the end cap is re-installed into the end of the
extension. Multiple 6” handle extensions can be used together to extend the
16” handle even further.
70-802
If extra weight in the handle is desired to counteract vibration and sudden yanks that are commonly experienced when turning, an optional solid steel Counterweight fits inside f the handle and is secured in place by the end cap. Lead pellets (buckshot) can also be used, as the handle cavity is sealed to prevent pellet spillage. 4-5/16” x 3/4”, 9 ounces.
70-803
The 16” handle’s chuck collar has a threaded side hole to install a Side Handle for extra holding stability, particularly when turning interiors of large bowls or platters. Pending how the shaft is installed in the chuck’s forward alignment holes, the side handle can be positioned for left-hand or right-hand use. 5-1/4” x 13/16”.
