140° V-Point
The 30559 family uses a solid-TC spiral with a verified 140-degree roof/V-point.


Titan SKU 30559-6-06036-L is retained as the commerce key for this inventory row. JSO's current official 30559 table identifies the matching 6 mm, 70 mm overall, left hand manufacturer configuration as Part-No. 30559-6-06038-L. The verified manufacturer geometry is D 6 mm, L2 38 mm, L4 1.1 mm, L1 70 mm, 10 mm shank, Z2 solid-TC spiral construction with a 140° V-point, clamping flat, and length-adjusting screw.
Exact JSO/Titan configuration verified against the current manufacturer family record and the supplied Titan commerce SKU.
Confirm Titan SKU 30559-6-06036-L and current JSO Part-No. 30559-6-06038-L, left hand rotation, 10 mm shank, 140° V-point, 70 mm overall length, holder/clamping-flat compatibility, and machine drilling parameters before use.

The official 30559 configuration uses a solid-TC spiral with a 140° V-point, 6 mm diameter, 38 mm cutting length, L4 1.1 mm, L1 70 mm, and a 10 mm shank with clamping flat and length-adjusting screw.
JSO specifies the family for through holes on nesting machines and blind holes in wood-based and plastic materials, with published material recommendations including HPL, laminated chipboard/MDF, multiplex, and solid wood.
Technical Specifications
The 30559 family uses a solid-TC spiral with a verified 140-degree roof/V-point.
JSO specifies through-hole work on nesting machines and blind-hole drilling on CNC/throughfeed equipment.
The left hand identity is retained and must not be substituted with the opposite-hand row.
Confirm Titan SKU 30559-6-06036-L and current JSO Part-No. 30559-6-06038-L, left hand rotation, 10 mm shank, 140° V-point, 70 mm overall length, holder/clamping-flat compatibility, and machine drilling parameters before use. Do not substitute a neighboring JSO row, hand, angle, coating, insert grade, screw size, or family simply because one or more dimensions appear similar.
This 30559 configuration combines D 6 mm, L2 38 mm, L4 1.1 mm, L1 70 mm, 10 mm shank, Z2 solid-TC spiral geometry, a 140° V-point, and left hand rotation.
Exact row and hand verification remain mandatory because nearby 30559 variants differ by diameter, cutting length, overall length, and left/right rotation.
