Regrinding

Tool Regrinding

Restore geometry, dimensions and cutting performance of carbide and HSS tools — on dedicated CNC grinding machines with ±0.005mm tolerance.

01 / ENDMILL
End Mill

Regrind carbide endmill (2–4 flutes), ball nose, bull nose — restore diameter, cutting length, helix angle and nose radius. Diameter tolerance ±0.005mm.

Carbide · HSS-Co · D2–25mm
02 / DRILL
Drill

Regrind carbide and HSS drills — restore point, tip angle (118°/135°), length, symmetry. HSS magnetic drills also accepted.

Carbide · HSS · D1–32mm
03 / REAMER
Reamer

Regrind carbide and HSS reamers with high precision — restore H6/H7 bore tolerance and roundness. Critical for precision fit parts.

Coating

PVD · DLC · Heat Treatment

Increase hardness, reduce friction, withstand high heat — choose the right coating for your workpiece material to maximize tool life.

A / NITRIDING

Nitriding

Increases HSS steel surface hardness to 900–1200 HV, diffusion layer 0.05–0.3mm. Reduces friction, extends tool life. No dimensional change.

B / BLACKENING

Steam Blackening

Steam oxidation (Fe₃O₄) — corrosion resistance, reduced glare, improved appearance. Layer 1–2µm, no effect on tolerance. Suitable for turning tools, fixtures.

Outgoing Inspection
Process

4-Step Standard Process

Step-by-step quality control — from intake to outgoing inspection.

01
Intake

Inspect actual tool condition, assess wear level, advise regrinding/coating solution and quote on the day.

02
Regrinding

Grind on dedicated 5-axis CNC tool grinder per OEM drawing. Tolerance ±0.005mm.

03
Coating / Heat Treatment

Place into PVD/DLC chamber or heat treatment furnace per technical specs for each coating type. Verify thickness and adhesion post-coating.

04
QC & Dispatch

Measure diameter, length, inspect cutting edges under magnification. Package and return with inspection certificate.

FAQ

Frequently Asked Questions

Can a carbide end mill with a broken tip be reground?
If the breakage is ≤3mm, we can grind it shorter and fully restore the geometry. Deeper breaks require a case-by-case assessment depending on the original diameter — send a photo first for a free consultation.
How long does each batch take?
Regrinding only (no coating): 24–48 business hours. Full regrind + PVD coating package: 3–5 business days depending on quantity and coating type. Rush orders can be arranged — contact us directly.
Which is better for hard steel — TiAlN or AlCrN?
AlCrN has superior heat resistance (up to 1100°C vs. 900°C for TiAlN), ideal for dry machining hardened steel >50 HRC or die casting molds. TiAlN is cost-effective for wet machining alloy steel and standard stainless steel.
Can tools be shipped from other provinces?
Yes. We accept nationwide courier shipments. Send photos and tool specs (original diameter, length, material, coating required) for a quote before physical shipment. Once confirmed, ship via J&T, GHTK, or ViettelPost.
How many times can a tool be reground?
A typical carbide endmill can be reground 3–5 times depending on wear level, original diameter, and tolerance requirements. Each regrind removes a small amount from the diameter or cutting length — we advise specifically when we receive the tool.
Can DLC coating be used for aluminum machining?
DLC is the optimal choice for aluminum, copper, and plastics. Hardness 4000 HV, low friction coefficient (0.1–0.15), non-reactive with aluminum so almost zero built-up edge. Combined with high helix flutes and high cutting speed for excellent aluminum surface finish.
