Product Overview
The N110056 Nose Cone / Gear Case Housing is a precision-engineered direct-fit replacement for the front transmission housing on 20V cordless impact drivers built on the DCF835 / DCF885 platform. This complete nose cone assembly (referenced as “NOSE SA” in OEM parts diagrams, item 7) encloses and protects the impact mechanism and gear train – the critical components that deliver the rotational force and impacting action for heavy-duty fastening applications.[reference:0][reference:1]
Designed for professional repair technicians and equipment maintenance specialists, this housing restores structural integrity to tools that have suffered drop damage, cracked gear cases, or worn nose cone assemblies. The high-impact engineered plastic construction with reinforced mounting bosses provides the durability required for daily jobsite use while protecting internal components from dust, debris, and impact damage.
This housing assembly is the direct replacement for the original equipment nose cone in DCF835, DCF835C2, DCF885, DCF885C2, and related 20V impact driver variants. It is referenced as item 7 in OEM parts diagrams and carries the OEM part number N110056.[reference:2][reference:3]
💡 Pro Tip – The Transfer Protocol: The N110056 nose cone assembly includes the housing only – the internal impact mechanism components (hammer, anvil, spring) must be transferred from the original housing. Before disassembly, photograph the internal component layout and note the orientation of each part. The impact mechanism uses specific spring tension and component alignment – incorrect reassembly will result in loss of impacting action or tool failure. Always remove the battery pack before beginning any disassembly.
Diagnostic & Fitment – When to Replace
Specification Comparison
| Specification | Worn / Generic Aftermarket | FixPartHub Precision Replacement ✅ |
|---|---|---|
| Material Quality | Low-grade plastic – brittle, prone to cracking | High-impact engineering plastic – jobsite durability |
| Mounting Boss Integrity | Weak bosses – strip easily during reassembly | Reinforced bosses – OEM-spec durability |
| Bit Retention Interface | Inconsistent – loose bit fitment | OEM-spec geometry – positive bit retention |
| Fitment | Vague or incorrect compatibility claims | DCF835 / DCF835C2 / DCF885 / DCF885C2 – direct-fit |
| Part Number Status | Generic cross-reference – uncertain quality | Active OEM N110056 – factory specification |

Diagnostic Q&A
❓ Q: My impact driver’s bit won’t stay locked – is the nose cone the problem?
A: Possibly. The 1/4″ hex collet retention mechanism is integrated into the nose cone assembly. If the collet is worn, the bit retention spring is damaged, or the collet fingers are deformed, the entire nose cone requires replacement. The N110056 is a complete nose cone assembly that includes the bit retention interface – replacing it restores positive bit locking.
❓ Q: What’s the difference between N110056 and just replacing the collet?
A: N110056 is a complete nose cone assembly containing the housing, bit retention mechanism, and the front impact mechanism housing. If the collet is the only worn component, you may be able to replace just the collet. However, if the housing is cracked, mounting bosses are damaged, or the nose cone shows signs of impact damage, the complete N110056 assembly replacement is required.
❓ Q: Will this nose cone fit my DCF885C2 model?
A: Yes. N110056 is the OEM nose cone assembly for DCF885C2, DCF885, DCF835C2, DCF835, and related 20V impact driver variants. It is referenced as item 7 in OEM parts diagrams for all these models.
❓ Q: What internal components need to be transferred from the old housing?
A: The impact mechanism components – including the hammer, anvil, impact spring, and associated washers – must be transferred from the original nose cone to the new N110056 housing. These components are not included with the nose cone assembly. Always photograph the component layout before disassembly to ensure correct reassembly.
Safety Notes
- 🔴 Always remove the battery pack before beginning any disassembly or housing replacement procedure.
- 🔧 Document internal component layout – the impact mechanism uses specific spring tension and component alignment. Photograph the assembly before disassembly.
- 🔩 Use correct torque values – housing screws typically require 0.8-1.2 Nm (7-10 in-lbs). Over-torquing can strip the reinforced mounting bosses.
- 🧤 Wear appropriate PPE – safety glasses when handling small components and springs.
- 📐 Verify impact mechanism alignment before final closure – the hammer and anvil must engage correctly for proper impacting action.
- ✅ Test function before full reassembly – insert battery and verify the tool operates correctly in forward and reverse before reinstalling the final screws.
A: The N110056 is a complete nose cone assembly (NOSE SA) containing the front gear case housing for 20V impact drivers. It encloses and protects the impact mechanism and gear train. The assembly includes the housing with integrated bit retention interface – internal impact components must be transferred from the original housing.
A: Yes. N110056 is compatible with DCF835, DCF835C2, DCF835M2, DCF885, DCF885C2, DCF885M2, and related 20V impact driver variants. It is referenced as item 7 in OEM parts diagrams for all these models.
A: No. The nose cone assembly includes the housing only. The internal impact mechanism components – hammer, anvil, impact spring, and associated washers – must be transferred from the original housing.
A: Common indicators include cracked or split housing from impact damage, broken mounting bosses that prevent secure closure, worn bit retention causing bits to fall out, or visible damage to the front housing that compromises tool structural integrity.
