What Are CNC Tool Holder Accessories?
Indexable tool holders (drill bodies, face mill arbors, chamfer holders) use replaceable inserts or cutter heads plus a small set of consumable parts that hold everything together. When you swap inserts, the screws, clamps, and pins take repeated torque cycles — eventually they wear, strip, or get lost. Keeping spare accessories on hand prevents production-line downtime when a screw head strips mid-job.
The 5 categories of tool holder accessories in this collection cover the full range of consumable parts across indexable drill bodies, face mill arbors, chamfer holders, and T-slot cutter bodies:
- Center pins (locating pins) — align inserts and cutter heads in the holder pocket. Spring steel for high-cycle production; stainless steel for corrosion resistance.
- M-type clamps (pressure plates) — clamp inserts or cutter heads into the holder. Composite (M-type HL-series) for vibration damping, replacement for OEM W-type clamps.
- Screws (fasteners) — GB70-85 slotted, M-series hex, plum (Torx) screws in stainless steel. Hold inserts / clamps / cutter heads in place.
- Carbide shims (seating shims) — sit under inserts to adjust seating height and protect the holder pocket from wear.
- Torx wrenches (drivers) — T7 / T8 / WH50L for M2.2 / M2.5 / M6 screw heads. Match the wrench to the screw type for proper torque.

Material Selection Guide
For center pins, the two main material options serve different environments. Pick the right material for your workshop conditions:
| Material | Best For | Properties | Common SKUs |
|---|---|---|---|
| Stainless Steel | Wet environments, coolant-heavy production, outdoor tool carts | Rust-proof, corrosion-resistant, slightly softer than spring steel | CTM510 / CTM511 / CTM513 / CTM515 / CTM613 / CTM617 / CTM618 / CTM619 / CTM822 (stainless variants) |
| Spring Steel | High-cycle production, dry machining, vibration-heavy cuts | Harder, higher fatigue resistance, slight rust risk in wet environments | CTM510-Spring / CTM511-Spring / CTM513-Spring / CTM515-Spring / CTM613-Spring / CTM617-Spring / CTM619-Spring |
| Carbide (shims) | Under VBMT / VCMT inserts for height adjustment | Extreme wear resistance, precision-ground flatness | V16BS diamond shim |
| Composite (clamps) | M-type clamps for vibration damping | Composite material reduces chatter, replaces OEM W-type metal clamps | HL1510 / HL1808 / HL1810 / HL1813 |

Frequently Asked Questions
Which center pin fits which holder body?
Each holder body has a specific center pin design. CTM5xx series (510 / 511 / 513 / 515 / 822) fits 2D/3D indexable drill bodies and chamfer holders. CTM6xx series (613 / 617 / 618 / 619) fits WC-insert indexable drills and larger chamfer holders. CT515-T and CT618-W fit W-type arbors for face mills. Send a photo of your holder pocket to our WhatsApp and we'll match the exact pin you need.
Stainless steel vs spring steel center pins — which should I pick?
Stainless steel for wet / coolant-heavy production or shops in humid climates — the rust-proof property extends pin life and prevents contamination of the holder pocket. Spring steel for dry machining, high-cycle production, and vibration-heavy cuts (face milling, deep drilling) — the harder material resists fatigue and lasts longer under repeated insert swaps. Both fit the same holder pocket — you can switch between them without modifying the holder.
Why 10-pc packs instead of single pieces?
The 10-pc pack format is the bulk-saving standard for consumable tool holder accessories. Screws strip, pins wear, clamps break, wrenches get lost — by the time you need a replacement, you usually need several. The 10-pc pack means you always have spares on hand for the next failure, and the per-piece price is 30-50% lower than buying singles from OEM. For very-low-volume users, we still ship single packs (1 unit = 1 pack of 10 pcs).
📦 Shipping cost & delivery time for individual buyers?
We ship to 50+ countries via DHL / UPS / FedEx. Most orders deliver in 3-7 business days. Shipping cost is calculated at checkout based on destination — typically $10-$25 for a 10-pc accessory pack to North America / Europe / Asia-Pacific. Tracking link is emailed within 24 hours of dispatch. We also ship to home addresses (not just commercial).
🛒 Can I order just 1 pack to try?
Yes — 1 pack (10 pcs) welcome. No MOQ, no bulk-buy requirement. Single-pack orders get the same DHL/UPS/FedEx tracked shipping as bulk orders. Volume discount is automatic in cart: 2-9 packs 6% OFF, 10+ packs 12% OFF — but you never have to hit those tiers to place an order.
⇆ Returns & warranty?
30-day return window for unused product in original packaging. If a part arrives damaged or defective, we ship a replacement free of charge (you keep the original). For dimensional mismatch (e.g. wrong thread pitch), send a photo to chao@cnchome-beyond.com or WhatsApp +86 15990663752 and we'll troubleshoot or replace.
