Built for weld cleanup, edge preparation, and controlled material removal with compact abrasive wheels, the Cleco C3135A4-38OH Right Angle Grinder pairs a 1.7 HP pneumatic motor with 13,500 RPM free speed for fast grinding on fabricated metal parts, repair components, and production assemblies. The 4″ wheel capacity helps operators work in tighter areas than larger 5″ grinders, while the 3/8″-24 spindle thread supports compatible Type 27, Type 27 threaded hub, and Type 1 abrasive discs when the wheel type and speed rating are properly matched.The 3.03″ head height gives this C31 Series grinder useful access around brackets, weldments, corners, and part geometry where clearance matters. Its rear exhaust overhose routes spent air away from the grinding area, helping reduce debris disturbance near the wheel contact point. A quick-change spindle lock, anti-vibration handle, dual-layer composite housing, and 270 adjustable guard make the tool practical for repeated abrasive changes and daily grinding work in fabrication, maintenance, and repair environments.Type: Right Angle Grinder | Series: C31 | Model: C3135A4-38OH | Power: 1.7 HP / 1.25 kW | Free Speed: 13,500 RPM | Wheel Size: 4″ | Spindle Thread: 3/8″-24 | Head Height: 3.03″ | Length: 8.95″ | Weight: 3.78 lb | Air Inlet: 3/8″ NPT | Minimum Hose I.D.: 1/2″ | Exhaust: Rear Exhaust OverhoseFeatures:1.7 HP motor provides strong grinding power for weld cleanup, deburring, and surface preparation work.13,500 RPM free speed supports efficient material removal with properly rated 4″ abrasive wheels.Quick-change spindle lock helps speed up wheel changes during repeated grinding or finishing tasks.Rear exhaust overhose helps route exhaust air away from the work surface and operator position.Anti-vibration handle helps reduce hand fatigue during longer grinding sessions.Dual-layer, high-impact composite housing helps protect the tool in active shop and production environments.270 adjustable guard allows the operator to reposition coverage for better access around edges, corners, and obstructions.Compatible with Type 27, Type 27 threaded hub, and Type 1 abrasive discs when wheel size, spindle thread, and RPM rating match the tool requirements.Made in USA: Applications:Metal fabrication: Grinding weld beads, smoothing cut edges, and preparing steel components before finishing or coating.Welding and repair shops: Removing spatter, blending small welds, and cleaning joint areas with compatible 4″ abrasive wheels.Industrial maintenance and MRO: Deburring machinery parts, removing corrosion, and cleaning repaired components during rebuild work.Transportation and equipment service: Grinding brackets, frame sections, panels, and fabricated assemblies where a smaller wheel improves access.Production workstations: Repeated edge cleanup and surface preparation where pneumatic power, rear exhaust, and fast abrasive changes support consistent workflow.FAQs:Q: What wheel size does the Cleco C3135A4-38OH use?A: This model is configured for 4″ abrasive wheels. Always confirm that the wheel type, spindle thread, guard, and maximum operating speed are compatible before mounting an accessory.Q: What does the 3/8″-24 spindle thread mean?A: The spindle thread identifies the threaded connection used to mount compatible abrasive hardware or threaded-hub discs. Accessories must match the 3/8″-24 thread and be approved for the grinders operating speed.Q: Why choose this 4″ model instead of a 5″ grinder?A: A 4″ grinder can be easier to position around smaller parts, weldments, brackets, and tight work areas. A 5″ grinder may cover more surface area, but this model offers better access where clearance is limited.Q: What is rear exhaust overhose?A: Rear exhaust overhose means spent air is directed through the rear of the tool and away from the grinding area. This can help reduce air blast near the abrasive contact point and improve work-area control.Q: What air hose should be used with this grinder?A: The listed minimum hose I.D. is 1/2″. Using hose that is too small can restrict airflow and reduce performance, especially during continuous grinding. .spec-accordion{width:100%;max-width:1200px;margin:1em auto;font-family:”Montserrat”,Arial,sans-serif;box-sizing:border-box} .spec-accordion *{box-sizing:border-box} .spec-accordion-toggle{width:100%;display:flex;justify-content:center;align-items:center;position:relative;background:#444;color:#fff;border:0;padding:14px 48px;font-family:”Bai Jamjuree”,Arial,sans-serif;font-size:16px;font-weight:700;text-transform:uppercase;cursor:pointer;text-align:center} .spec-accordion-toggle::after{content:”+”;font-size:22px;position:absolute;right:18px} .spec-accordion.open .spec-accordion-toggle::after{content:””} .spec-accordion-panel{display:none!important;width:100%;padding:16px 0 0} .spec-accordion.open .spec-accordion-panel{display:block!important} .spec-accordion-panel[hidden],.spec-accordion:not(.open) .spec-accordion-panel{display:none!important} .spec-table-wrapper{width:100%;max-width:1200px;margin:0 auto;overflow-x:visible!important;overflow-y:visible!important} .spec-table{width:100%!important;max-width:1200px;min-width:0!important;margin:0 auto;border-collapse:collapse;table-layout:fixed;font-family:”Montserrat”,Arial,sans-serif;font-size:12px;color:#000} .spec-table th{background:#444;color:#fff;text-transform:uppercase;font-family:”Bai Jamjuree”,Arial,sans-serif;font-weight:700;font-size:11px;padding:8px 4px;border:1px solid #ddd;text-align:center;line-height:1.15;white-space:normal;word-break:break-word} .spec-table td{padding:6px 4px;border:1px solid #eee;text-align:center;line-height:1.15;white-space:normal;word-break:break-word} .spec-table tbody tr:nth-child(even){background:#f7f7f7} .spec-table tbody tr:hover{background:#e5e5e5} .spec-table a{color:#0066cc;text-decoration:none;font-weight:600;background:transparent;padding:0;border-radius:0;box-shadow:none} .spec-table a:hover{text-decoration:underline} @media(max-width:640px){.spec-accordion,.spec-table-wrapper,.spec-table{width:100%;max-width:100%}.spec-accordion-toggle{font-size:14px;padding:13px 48px}} .spec-accordion.is-mobile-table .spec-table-wrapper{overflow-x:visible!important;overflow-y:visible} .spec-accordion.is-mobile-table .spec-table{width:100%;max-width:100%;min-width:0!important;border:0} .spec-accordion.is-mobile-table .spec-table thead{display:none!important} .spec-accordion.is-mobile-table .spec-table,.spec-accordion.is-mobile-table .spec-table tbody,.spec-accordion.is-mobile-table .spec-table tr,.spec-accordion.is-mobile-table .spec-table td{display:block;width:100%} .spec-accordion.is-mobile-table .spec-table tr{margin-bottom:14px;border:1px solid #ddd;background:#fff} .spec-accordion.is-mobile-table .spec-table tbody tr:nth-child(even),.spec-accordion.is-mobile-table .spec-table tbody tr:hover{background:#fff} .spec-accordion.is-mobile-table .spec-table td{display:flex;justify-content:space-between;gap:14px;text-align:right;border:0;border-bottom:1px solid #eee;padding:10px 12px;font-size:13px;word-break:break-word} .spec-accordion.is-mobile-table .spec-table td::before{content:attr(data-label);font-weight:700;text-transform:uppercase;color:#444;text-align:left;flex:0 0 46%} .spec-accordion.is-mobile-table .spec-table td>a{word-break:break-word} Available Variations and SpecificationsSKUEXHAUSTFREE SPEEDABRASIVE CAPACITY GRINDERSPINDLE SIZEWEIGHTLENGTHHEAD HEIGHTAIR INLET SIZER/MINLBINININC3120A45-58OHRear120004.5 Type 1 and Type 275/8 – 113.988.953.033/8 inC3120A45-M14OHRear120004.5 Type 1 and Type 27M14 x 23.988.953.033/8 inC3120A5-58OHRear120005 Type 1 and Type 275/8 – 114.058.953.033/8 inC3120A5-M14OHRear120005 Type 1 and Type 27M14 x 24.058.953.033/8 inC3135A4-38OHRear135004 Type 1 and Type 273/8 – 243.788.953.033/8 in (function(){ function initSpecAccordions(){ document.querySelectorAll(“.spec-accordion”).forEach(function(a){ if(a.dataset.specAccordionInit===”true”)return; a.dataset.specAccordionInit=”true”; var b=a.querySelector(“.spec-accordion-toggle”),p=a.querySelector(“.spec-accordion-panel”); if(!b||!p)return; var u=false; function m(){return(a.getBoundingClientRect().width||window.innerWidth)
