Wood Lathe Tools and Accessories

How to choose carbide turning tips and lathe accessories

Choose a turning tip by the shape of the cut, then by size. Geometry decides what the tip can physically do: a round tip rolls through curves, a square tip works straight sides and flat faces, and the single pointed tip cuts lines a round or square edge cannot reach. Size changes how much edge is in the cut – more edge removes material faster but pulls harder on the bar and on the operator. This category holds 8 HOLZMANN items: six carbide tips and two eccentric clamping systems.

Round, square or pointed

Round tips are the general-purpose choice for bowls, coves and beads, in three sizes: Ø 6 mm on the 10015511 for tight coves, narrow beads and detail, Ø 12 mm on the 10015506 as the middle size, and Ø 16 mm on the 10015509 as the roughing and hollowing tip with the longest curved edge. Square tips take the straight work: 15 x 15 mm on the 10015508 gives about a third more edge per side than the 11.3 x 11.1 mm 10015510, at 0.05 kg of carbide against 0.02 kg. The 10015507 is the only pointed geometry here, a 28 x 10 mm diamond for V-grooves and decorative lines.

Size, resistance and the tool you are holding

Match tip size to the bar and to the operator, not only to the workpiece. A large tip such as the Ø 16 mm 10015509 or the 15 x 15 mm 10015508 puts more edge in the cut, which is what brings a rough blank down to shape but also what generates the most resistance; on a light bar that resistance becomes a fight. The small square 10015510 and the Ø 6 mm 10015511 pull less and stay controllable on light tools and small work. Most turners end up with one large and one small tip of each geometry rather than one compromise size.

Coating

Coating is listed on part of the range rather than all of it: HOLZMANN publishes the 10015506, 10015507, 10015508 and 10015509 as titanium plated or titanium coated. Coating matters most for edge life on abrasive and resinous timber and least on short work in clean softwood. Confirm the finish of the tip you want on the quotation rather than assuming every article carries the same coating.

Holding the work: two eccentric clamping systems

Workholding is the accessory decision here, and HOLZMANN gives both eccentric clamping systems the same job – fixing heavy and unbalanced turning pieces on a wood lathe. The difference is reach and stiffness. The ES25070 is the compact unit at ML 70 mm on Ø 25 mm and 1 kg net; the ES30110 carries on where the ES25070 runs out, at ML 110 mm on Ø 30 mm and 1.5 kg net, with 40 mm more length and 5 mm more diameter to resist deflection a shorter unit would allow.

What to budget alongside the tips

Budget the holder, the lathe and the safety kit as separate lines. Carbide tips are cutting inserts – they need a turning bar or holder to sit in, and the fixing screw is what wears first, so a spare screw and driver is worth adding. Tips are indexed and replaced rather than reground like high-speed steel gouges, so treat them as a running cost and order more than one of the geometry you use most. Face protection, and an eccentric clamping system if you turn unbalanced blanks, complete the working set.
