How should KARBID threading inserts be selected?

KARBID threading insert selection should consider internal or external threading, right- or left-hand cutting, profile standard, pitch, material and surface requirements together.

What do the 16ER and 16IR product codes mean?

16ER generally refers to external threading inserts and 16IR to internal threading inserts. Different codes cover profile standards such as ISO, 55-degree, 60-degree, Whitworth, BSPT, NPT, TR and ACME.

Which applications use Pikko tools?

Pikko tools are considered for small-diameter internal turning, mini boring, grooving, internal profiling and precision small-part applications.

Which products does the KARBID grooving and parting-off catalogue cover?

The KARBID grooving and parting-off catalogue covers insert and holder families for grooving, parting-off, circlip grooves, face grooving, internal grooving and certain threading/cutting applications.

How should a thread mill be selected?

Thread mill selection should consider thread size, pitch, machining depth, hole type, material, machine rigidity and target cycle time together.

Threading Inserts

KARBID threading inserts are selected according to external or internal threading, right- or left-hand cutting, profile standard and pitch range. The catalogue includes ISO metric, 55-degree, 60-degree, Whitworth, BSPT, UN, NPT, RD30, TR, ACME and STACME profile groups.

Example codes: 16ER1.00ISO, 16ER1.25ISO, 16ER1.50ISO, 16ER2.00ISO, 16ER3.00ISO, 16IR1.00ISO, 16IR1.50ISO, 16IR2.00ISO, 22ER3.50ISO, 22ER4.00ISO, 22IR4.00ISO.

General thread profiles

For non-standard or special thread profiles, the correct insert profile, gauge compatibility and pass strategy are critical. Incorrect profile selection can cause dimensional errors, surface problems and tool breakage.

Example codes: 16ERA55, 16ERAG55, 16ERG55, 22ERN55, 16ERA60, 16ERAG60, 16ERG60, 22ERN60, 16ER8W, 16ER11W, 16ER14W, 16ER19W, 16ER14BSPT, 16ER19BSPT, 16ER28BSPT.

Thread Mills

KARBID thread mills are considered for metric thread milling, process flexibility in blind or through holes, more controlled machining of different diameter/pitch combinations and fewer tool changes. Selection should consider 2XD/3XD machining depth, single-flute/three-flute/multi-flute construction, minimum hole diameter, shank diameter and material together.

Example codes: BM3F-M1.2-0,25-3,4-50, BM3F-M3.0-0,50-6,2-50, BM3F-M6.0-1,00-12,5-57, BM3F-M8.0-1,25-24,6-63, BM1F-M1.2-0,25-3,6-50, BM1F-M5.0-0,80-16,0-45, BMMF-M3.0-0,50-6,0-50, BMMF-M6.0-1,00-12,0-50, BMMF-M10.0-1,50-21,0-60.

Turning Cutters

The KARBID turning cutters catalogue supports selection of suitable holders and cutting tools for turning operations. Tool rigidity, workholding, approach angle and insert compatibility should be assessed together for external turning, internal turning, facing, grooving and general metal removal.

Product selection in this group is generally based on the current holder dimensions, insert shape, workpiece material, depth of cut and target surface finish.

Pikko Tools

Pikko tools are considered for small-diameter internal machining, mini boring, grooving, internal profiling and precision small-part production. The catalogue contains many product families with different minimum hole diameters, lengths and geometries.

Example codes: MGR3B1.0L10, MGR5B1.5L15, MFR4B1.0L15, MFR5B2.0L22, MPR3R0.2L15, MIR4L15A55, MIR6L15A60, MUR4R0.2L15, MUR8R0.2L25, MTR3R0.2L15, MQR4R0.2L15, MZR5R0.75L22, MXR5R0.2L22, MKR6R0.75L15.

Grooving and Parting-Off

The KARBID grooving and parting-off catalogue covers insert and holder families for external grooving, internal grooving, face grooving, parting-off, circlip grooves, full-radius grooves and certain special threading/cutting applications. Selection should consider groove width, depth of cut, minimum diameter, right-/left-hand cutting, holder dimensions and chip evacuation together.

Example codes: K-BCF32, K-BCA43, K-T11, K-T16, K-GR, K-GER/L-A/B, K-GER/L-C/D/E, K-GER/L-DD/EE, K-VNF, K-VC11, K-VC16, K-FVC1604, K-MB, K-TKF12/16, K-CTP/K-CTPA, MGMN, MRMN, MGGN, TDC/TDJ, DGN/DGR, K-TQJ27, K-PENTA24N, K-PENTA34N, K-TTX32, K-TT32, K-TKFT, K-TTP/K-TTPA, K-TKFB, K-ABS/K-ABW.

Which KARBID solution fits your needs?

Selecting a KARBID product is a process decision that goes beyond finding a catalogue code. The right product should meet dimensional accuracy, surface finish, tool life and cost-per-part targets.

Surface and dimensional problems in threading

Surface finish and dimensional stability suffer when thread standard, pitch, internal/external threading and pass strategy do not match. The 16ER/16IR and 22ER/22IR families should be selected according to the profile standard.

BSPT, NPT, Whitworth and special profiles

In pipe threading and special profile applications, the profile standard is as important as the product code. BSPT, NPT, Whitworth, TR and ACME applications require the correct insert profile.

Process flexibility with thread milling

Thread mills are useful for producing the same pitch at different diameters, controlling chips in blind holes and reducing cutting forces. BM3F, BM1F and BMMF families should be selected according to depth, flute count and cycle time.

Small-diameter internal machining

Pikko mini boring products are considered to address access, vibration and chip evacuation problems in small-diameter internal turning and grooving.

Tool life in turning

Improving tool life requires joint assessment of the cutting edge, holder rigidity, clamping and distribution of cutting passes. We select turning cutters using data from the existing operation.

Stability in grooving and parting-off

Vibration and edge chipping increase when groove width, depth of cut, part diameter, holder overhang and chip evacuation are poorly matched. Insert and holder should be assessed together when selecting grooving and parting-off tools.

Reducing costs in series production

The right KARBID tool should be assessed using cycle time, tool life, scrap rate and operator setup time as well as purchase price.

Alternative products for an existing operation

KARBID alternatives can be assessed against your current insert or holder code. The aim is to improve the operation's outcome as well as find an equivalent product.

Common requirements for KARBID products

KARBID products are usually considered to solve a specific problem in threading, thread milling, turning or small-diameter internal machining. The 16ER and 22ER families are assessed for external threading; 16IR, 22IR and 11IR inserts are assessed for internal threading according to the profile standard.

For thread profiles such as BSPT, NPT, Whitworth, TR, ACME and ISO metric, thread direction, pitch, tolerance, material and pass strategy should be assessed alongside the product code. For thread mills, selection considers the thread milling strategy, 2XD/3XD depth, single- or multi-flute construction and target cycle time.

Balkanlar Mühendislik support for KARBID product selection

Selecting the right KARBID product requires more than finding a catalogue code. The solution emerges by assessing the thread standard, operation direction, thread milling depth, groove dimensions, tool rigidity, workholding, material and target surface finish together.

At Balkanlar Mühendislik, we assess KARBID threading inserts, thread mills, turning cutters, grooving and parting-off, and Pikko tools alongside time studies, machining time improvement, cost analysis and custom tooling. Our aim is to help operations run more reliably, measurably and economically.
