Single-hole blade blocks
Square or rectangular blocks with one central or offset mounting hole. Confirm the hole diameter, thread and seat position.
Steel Bar Cutting Machine Replacement Blades
Rebar Cutter Blades
Replacement and custom blade blocks for GQ40, GQ50 and similar rebar cutter machines. Confirm the dimensions, hole pattern, mounting profile and material from your old blade or approved drawing before production.
Single-, two- and four-hole formsArc-notched profilesDrawing or sample matching
GQ40 and GQ50 are reference machine types, not a universal cross-reference. The correct replacement depends on the actual mounting seat and blade geometry.
Request a Fit Review
A replacement blade starts with the machine fit
Rebar cutter blades may look similar while using different hole layouts, thicknesses, threads or mounting profiles. Use the product family as a starting point, then verify the part against the machine.

Supply routeReference sizes or custom fitment
Blade configurations for replacement and custom supply
The supplied product material shows several block shapes and mounting patterns. These are configuration families, not interchangeable parts.
Two-hole blade blocks
Two-hole forms with different spacing and thickness options. Hole centre distance must be checked against the old blade.
Four-hole blade blocks
Four-hole square configurations shown in the supplied references. Confirm hole count, countersink and clamping direction.
Arc-notched blade blocks
Profiles with a curved or relieved mounting opening. The notch geometry and effective cutting edge must be measured, not inferred from a photo.
Material options and custom model references
The supplied material reference shows multiple steel options and supports drawing-based customization. Final steel grade, heat treatment and model fit should follow the approved drawing, old blade or quotation.
H13 steel reference
H13 is listed in the supplied product title and material reference. Confirm the required grade for the selected blade geometry and working condition.
CR12MoV reference
CR12MoV is shown as another material reference for selected blade forms. The final grade must be tied to the approved order specification.
T10 steel reference
T10 is also listed in the supplied material. Confirm the required heat treatment and hardness target before production.
Drawing-based customization
Send a drawing, old blade or measured sample for custom outline, holes, notches, dimensions and cutting orientation.
The source image also contains the label “DL”; this label needs supplier or drawing confirmation before it is presented as a verified material grade. No universal hardness range is published here.
Reference dimensions shown in the supplied material
These examples help start a quotation. They do not replace a drawing, old blade or machine measurement.
| Configuration family | Reference dimensions | Fitment details to confirm |
|---|---|---|
| Single-hole blocks | 78×78×17; 83×83×16; 83×83×17; 90×90×20; 70×70×25 mm | Hole diameter, thread, centre position and thickness |
| Multi-hole square blocks | 83×83×26; 90×90×26; 100×100×28 mm | Hole count, spacing, countersink and mounting direction |
| Arc/notched blocks | 95×83×26; 105×90×26; 83×83×26 mm | Notch opening, radius, edge position and seat clearance |
| Long or larger blocks | 150×80×30; 200×100×28; 215×120×30; 240×80×26 mm | Full outline, hole pattern and machine installation space |
Dimensions are reference examples extracted from the supplied product material. Confirm all dimensions and hole details before production.
How to measure a rebar cutter blade
Measure the blade before requesting a replacement or custom match. The key dimensions are width, height, thickness and hole spacing.
Fitment guide
Record the complete mounting profile
Take measurements from the old blade or an approved drawing. Record the outside width and height, the blade thickness and the centre-to-centre distance between mounting holes.
- Width and overall height
- Blade thickness
- Hole diameter and hole spacing
- Notch, edge and seat details
A product photo is a starting point only. Please send the measured dimensions together with the machine model or old blade photos so the mounting fit can be reviewed.
What to send for a reliable fit review
A clear old-blade photo is useful, but a drawing, measured sample or machine reference gives a more reliable match.
01
Machine model
Send the machine brand, GQ model and nameplate photo when available.
02
Blade outline
Measure length, width, thickness and every arc, relief or notch.
03
Hole pattern
Record hole count, diameter, thread, spacing, edge distance and countersink details.
04
Installation position
Show the blade seat, cutting orientation and how the part is clamped.
05
Material requirement
Share the current steel grade, hardness requirement or working condition if known.
06
Quantity and destination
Confirm pieces or sets, destination country and any packing requirement.
Applications
Use the application as context for the blade review, not as a substitute for the machine fitment check.
Construction rebar processing
Replacement blade blocks for equipment used to cut steel bars during construction and fabrication work.
Scrap rebar cutting
For cutting recovered or waste steel bars when the machine, feed condition and blade geometry are confirmed.
Machine replacement parts
For maintenance teams that need a replacement set matched to the existing blade seat and mounting pattern.
Rebar cutter blade questions
Short answers for replacement and custom-supply buyers.
Are these blades compatible with every GQ40 or GQ50 machine?
No. GQ40 and GQ50 are reference machine types. Confirm the actual dimensions, hole pattern, mounting seat and cutting orientation before production.
Can you make a replacement blade from an old sample?
Yes, subject to a clear sample, drawing or complete fitment information. Photos alone may not show the hole depth, thread or seat geometry.
Which materials are available?
The supplied reference material lists H13, CR12MoV and T10. The final grade and any heat-treatment requirement should be confirmed for the approved configuration.
What dimensions are available?
The page shows reference examples from the supplied product material. They are not a universal size list; send the old blade or drawing for a precise match.
Can you make arc-notched or threaded blade blocks?
The supplied references show notched profiles and threaded or countersunk mounting details. Confirm the complete outline and hole geometry before quotation.
What information is needed for a quotation?
Provide the machine model, blade photos or drawing, dimensions, hole pattern, material requirement, quantity and destination.
